How To Choose The Best Dog Food For Intestinal Problems

Intestinal trouble in dogs rarely announces itself politely. The stool softens first, then appetite dips, then you are standing in the kitchen at 6am wondering what to feed a dog who will not eat. The food you choose is the single biggest lever you control.

Start With Consistency, Not Novelty

Dogs with delicate guts do best on the same formula, fed at the same times, day after day. Every switch restarts the adjustment clock. When you do switch — whether from one kibble to another or into a bland diet during a flare-up — stretch it over 7–10 days, mixing a little more new food into the old each day. That slow ramp is the difference between a settled stomach and a second round of loose stool.

Read The Fat Line First

Fat is the hardest nutrient for an inflamed gut to handle, so a lower fat content tends to sit gentler. Dave’s Pet Food publishes just 6% crude fat on its bland diet — the kind of number worth hunting for when your dog is mid-flare. For everyday feeding, moderate fat plus highly digestible protein is the goal.

Wet Or Dry — Match The Moment

Wet bland diets shine during a flare-up: soft pâté is easy to swallow, easy to hide a pill in, and easy to portion small. Dry kibble wins for long-term feeding and for keeping a big-breed grocery bill sane. Many owners keep both and mix them.

Watch Fibre And Prebiotics

Fibre feeds the good bacteria in the gut and firms up stool. Psyllium husk, pumpkin, and prebiotic blends all serve that purpose. Some dogs need more fibre; a few need less. Check the guaranteed analysis and adjust under your vet’s guidance — never guess on a dog who is actively unwell.

Prescription Versus Off-The-Shelf

A true prescription diet is formulated for medical conditions and requires a vet’s authorization. An off-the-shelf limited-ingredient or bland diet is for milder, ordinary upset stomachs and transitions. If your dog has been diagnosed with pancreatitis, fat intolerance, or a similar condition, the prescription route is the safe one — and a vet’s recommendation should always come first.

In‑Depth Reviews

★ Best Overall

1. Hill’s Science Diet Puppy Sensitive Stomach & Skin Dry Dog Food

Our pick — over 4.5★ from 850+ verified ratings; the strongest balance of quality and price.

Veterinary Formulated13 lb Bag

The salmon-first kibble that gets a sensitive puppy eating and digesting again

If you have a puppy whose gut has never quite settled, this is where most owners end up — and happily. It carries a 4.7-star rating across 800+ reviews, the strongest combination of score and volume on this list. High-quality salmon is the number-one ingredient, and the formula layers prebiotic fibre for gentle digestion on top of Vitamin E, omega-3, and omega-6 for skin and coat.

What keeps owners coming back is how eagerly picky puppies take to it. Reviewers describe puppies who are “very sensitive to other foods” absolutely inhaling the bowl. A six-month Chihuahua with a skin issue that had not responded to a rival food turned around fast on this kibble — the scratching stopped, appetite returned within two days, and the skin cleared inside about a week. Bigger-picture, dogs on this food produce smaller, less frequent stools, which is exactly the sign of a gut absorbing more of what it eats.

The honest trade-off is value. Some owners call it pricey, and a few notice a slight smell to the kibble. Neither keeps people from reordering. The bag is a 13-pound dry formula and the small round kibble suits puppy teeth, so you are not guessing at portion size during growth.

What owners keep raving about

  • Salmon is the first ingredient, with prebiotic fibre for gentler digestion and easier nutrient absorption
  • DHA supports healthy brain development while high-quality protein fuels growing muscles
  • Puppies who reject other foods eat this one eagerly, per owner feedback

Where it asks you to compromise

  • Cost draws mixed feelings — several owners call it expensive compared to alternatives
  • A faint kibble odor shows up in owner comments
  • Formulated for puppies only, so adult dogs need the adult version

Made for: the puppy home where soft stools and itchy skin often arrive together.

Steer past it: grown dogs — this one is a puppy formula, and adults need a different fit.

Best Value

2. KOHA Limited Ingredient Bland Diet for Dogs, Chicken & White Rice Recipe

Limited IngredientNo Cooking Necessary

A ready-to-serve chicken and rice bowl for the nights your dog cannot keep anything down

When a vet says “feed her chicken and rice for a few days,” this is the shortcut. KOHA’s bland diet is a wet limited-ingredient food with a single protein source — chicken — plus white rice and pumpkin to support healthy stools and regularity. It is formulated for loose stool and diarrhea, and it is pea-free, potato-free, soy-free, and free of artificial preservatives.

Owners lean on it hard during flare-ups. It “helped my dog recover when she had a bad bout of diarrhea,” and she tolerated it well — and the same household’s older dog with kidney issues loves it too, which says a lot about how broadly it lands. A vet suggested it as a supplement when a dog needed to skip regular kibble for a few days, and the small portions gave that dog the nutrition it needed without overloading the gut. It can also be used as a topper, fed twice daily alongside regular kibble for a senior dog with a sensitive stomach.

One recurring gripe: the texture and flavour split owners. A handful of picky dogs turn their noses up, and some note it costs more than throwing chicken in a pot yourself — though most argue the convenience and the correct ingredient ratios are worth it. Portability is a quiet strength here too; a pouch of this in the car beats trying to cook on a road trip.

Why it earns a spot: if you have ever stood in a kitchen at 10pm boiling rice with a sick dog, you already understand the value of a ready-to-serve bland diet. KOHA strips the formula down to chicken, white rice, and pumpkin — nothing junky for a raw gut to react to.

The fair warning: it is billed for chronic upset stomachs and flare-ups alike, but it is a wet food with a limited shelf life once opened, so you will want to refrigerate and use it up quickly.

Reach for it when: your dog is mid-flare and needs something gentle right now.

Look elsewhere if: your dog has been diagnosed with a specific condition needing a prescription formula.

Most Versatile

3. Dave’s Pet Food Bland Diet Dog Food, Chicken & Rice, 13.2 oz, 12 pk

6% Crude FatLow Fat

Low-fat cans that double as an everyday meal and a rescue ration during a gut emergency

Only 6% crude fat is the number that does the heavy lifting here. That is a genuinely low figure, and it is why Dave’s is the can owners keep on the shelf for both daily feeding and flare-ups. The recipe is chicken, white rice, and essential vitamins and minerals — no wheat, gluten, artificial flavours, colours, or meat by-products — and it is AAFCO-compliant for adult maintenance, so it can be fed as a full meal long-term or spooned over kibble as a topper.

The pâté texture is soft and moist, easy to chew and swallow — a real plus for seniors, small breeds, and dogs with dental sensitivity. Owners describe a 12-year-old Rottweiler with two years of digestive trouble who stopped gurgling, doubled intake, and kept food down on this diet. A rescue puppy battling giardia, worms, reflux, and vomiting ate it eagerly, and the owner reports it settled the stomach and even hid an antacid pill. Another owner uses it to tempt an elderly chihuahua mix during pancreatitis flare-ups.

The practical note: this is an adult formula, not for puppies — and a few owners find it overpriced per can. Buyers also recommend chopping the pâté so fast eaters do not gulp it down and risk bloating. Kept refrigerated, an opened can stays good for two to three days, and portions freeze well for smaller dogs.

The case for Dave’s

  • Low 6% crude fat is gentle on dogs prone to vomiting, gas, and diarrhea
  • AAFCO-compliant for adult maintenance, so it works as a full meal or a topper
  • Soft pâté suits seniors, toy breeds, and dogs with dental sensitivity
  • No gluten, no artificial colours or flavours, no meat by-products

Where it falls short

  • Not formulated for puppies
  • Per-can cost draws mixed reviews — some owners call it overpriced
  • Open cans need refrigeration and quick use, which never suits a multi-bag household feeding large dogs

skip it if: your dog has been diagnosed with a specific medical condition your vet wants managed with a prescription diet.

Yes, if: your dog is prone to stomach upset, or your household needs a convenient food that doubles as a bland-diet option for travel, boarding, or post-surgery recovery.

Vet Formula

4. Royal Canin Veterinary Diet Canine Gastrointestinal LF Low Fat – 6.6lb

Prescription OnlyLow Fat

A vet-exclusive kibble built to keep fat-sensitive guts calm and stools firm

Royal Canin’s Gastrointestinal Low Fat is a prescription-only dry diet for dogs with diagnosed digestive concerns. It is low in fat and easy to digest, made with prebiotics to support good gut bacteria and a blend of dietary fibres to help with stool quality. If your dog has been diagnosed with fat intolerance or pancreatitis, this is the class of food the vet will usually reach for.

Owners of dogs on lifelong low-fat diets are the loudest fans. One household managing a dog with severe pancreatitis found the canned version caused near-vomiting while the dry version, fed in a careful schedule, cut feedings down and stopped the vomiting. Another owner saw firm stools return after days of diarrhea. There is weight-management appeal here too — a beagle mix needing to drop weight went on this formula, and the dog loves the taste.

Two things to know before you commit: this is a grocery expense, not a bargain, and it requires a vet’s prescription. A few dogs gain no weight benefit even while enjoying the food, so if your dog’s issue is weight loss rather than weight gain, this is worth flagging to your vet. Some owners also find the texture better accepted when mixed with the matching wet formula.

The real strength: it is a low-fat, highly digestible formula with prebiotics for gut bacteria support and dietary fibre for stool quality — the kind of composition that shows up in dogs with genuinely complex digestive histories, not just a passing soft stool.

What to weigh: cost and the prescription barrier. Neither is a flaw in the food — they are simply the reality of managing a dog on a therapeutic diet, and both are worth discussing with your vet.

Best for: dogs with vet-diagnosed fat intolerance, pancreatitis, or chronic GI conditions.

Not the one for: healthy dogs with occasional tummy trouble — that is the off-the-shelf shelf.

Grain-Free Fish Pick

5. Forza10 – Intestinal Dry Dog Food for Sensitive Stomachs, 8.8 lb

Fish ProteinGMO-Free

The anchovy-based kibble for dogs who cannot handle chicken

If your dog has always done poorly on chicken — itching, loose stool, or both — this is the pick to look at. Forza10’s Intestinal formula uses wild-caught anchovies as the protein, plus oregano, rose hips, and psyllium seed husk for digestion. It is free from GMOs, by-products, wheat, soy, artificial colours, and flavours, and it is designed for diarrhea, vomiting on an empty stomach, and flatulence.

Owners with chicken-allergic dogs report remarkable turnarounds. One switched from a costly rival brand over four days and saw bloating drop and solid stool return. Another describes a dog that “hasn’t had a single issue since” — eating it for over four months. A Frenchie owner who had tried everything calls it “the best.” Multiple buyers report it works as well as the prescription diet their vet had recommended.

The honest caveat is that this is a strongly flavoured fish kibble, and some dogs will refuse it outright. Reviewers with multiple dogs describe most of their pack disliking the flavour but eating it happily when it is mixed with a topping or fed 50/50 with another food. One owner also flagged the published fibre content as lower than the psyllium in the description would suggest, and went back to a higher-fibre food as a result.

Where Forza10 wins

  • Wild-caught anchovy as the protein — no chicken for allergic dogs to react to
  • Psyllium husk, oregano, and rose hips added to support digestion
  • GMO-free, wheat-free, soy-free, with no artificial colours or flavours

Where it splits opinion

  • Fish flavour is polarising — multiple dogs may turn it down unless it is topped
  • Published fibre content is lower than some owners expected given the psyllium in the recipe
  • Premium price for an 8.8-pound bag

Worth the try: if your dog has reacted badly to chicken and you suspect the protein is the trigger.

Give it a pass if: you need a highly-fibrous formula — this one runs lower than its description implies.

Prescription Wet Food

6. Hill’s Prescription Diet i/d Digestive Care Wet Dog Food

ActivBiome+ Digestion9.4 lb Case

The vet’s go-to wet food for settling a serious digestive upset fast

Hill’s Prescription Diet i/d is formulated by Hill’s nutritionists and veterinarians to help settle digestive upsets in adult dogs. The headline technology is ActivBiome+, a proprietary blend of prebiotic fibres a prebiotic fibre blend that feeds gut bacteria. It also carries high levels of B vitamins and added electrolytes to replace the nutrients a dog loses during stomach upset, plus antioxidants, and omega-3 and omega-6 for skin and coat.

For dogs in real trouble, owners mention it makes a visible difference. One dog with significant digestive issues tolerated it “from the start” and got back to normal. Another had been sick for 14 days and started eating and regaining weight once the wet was mixed with dry. A Pug with chronic digestive issues stays well while on it. The chicken and vegetable stew flavour is a plus for dogs who find plain kibble boring.

Two things to budget for: the cost, which owners widely call high, and pickiness. Not every dog will eat it — some flatly refuse. It is a prescription diet, so it needs a vet’s authorization, and small-can buyers occasionally run into stock gaps that force them into larger sizes.

Why vets reach for it: the ActivBiome+ prebiotic blend, B vitamins, and added electrolytes are designed for dogs who have been losing nutrients through vomiting or diarrhea — this is the food for the acute phase, not the everyday bowl.

The honest catch: cost is the biggest single complaint owners raise, and if your dog turns up its nose at the stew, it is money wasted. Worth trying a small quantity first if you are unsure.

Reach for this if: your vet has recommended a therapeutic digestive diet for an active upset.

Look elsewhere if: your dog is simply a little picky on a normal day — that is not a case for a prescription formula.

Crowd Favorite

7. Purina Pro Plan Sensitive Skin & Stomach Dry Dog Food, Salmon, 30 lb Bag

Live ProbioticsSalmon First

The 30-pound salmon formula that keeps sensitive dogs eating, plain, for months

Real salmon is the first ingredient here, and it is paired with oatmeal — a digestible grain that goes easy on the system — plus guaranteed live probiotics for digestive and immune health, and sunflower oil rich in omega-6 for skin and coat. This is the formula most sensitive-stomach owners arrive at eventually, and the wide review base is a strong safety net: the vast majority of customers note their dogs thriving on it.

Skin-allergy stories are the standout. A French Bulldog with itching, ear infections, and foot-biting improved after switching to this salmon-based food — enough to wean off ear drops. Another dog with daily hot spots and constant ear infections cleared up on Purina’s 28-day challenge, with the skin clear and ear infections gone by day 10. Chicken-free composition is the reason many owners land here in the first place; one owner’s dog had reacted badly to a liver-flavoured food containing chicken, and the switch to this chicken-free formula improved the condition.

Every formula has a split. A number of dogs do refuse it, and a small slice of reviewers point out their dog getting sick from it — worth watching during the 7–10 day transition. The other common note is price: this one runs expensive for a big-bag dry food, and a senior-formula buyer specifically knocked a star for that. The 30-pound bag is a serious commitment in the garage, but for multi-dog homes it also means fewer reorders.

Why it holds a top spot

  • Real salmon as the first ingredient with proven appeal to picky dogs
  • Oatmeal is gentle on the digestive system, and live probiotics support gut and immune health
  • Chicken-free — a strong choice for dogs with poultry sensitivities
  • 30-pound bag cuts the frequency of reorders for bigger households

Where to be careful

  • Not every dog takes to the salmon flavour, and a small share of dogs react poorly
  • Owners widely flag the price as high
  • Large bag means commitment — the food can go stale if you have just one small dog

Yes, if: chicken tends to be the trigger for your dog, or you are managing a skin and digestion issue together.

Hold off if: you have a single small dog who takes months to work through a 30-pound bag — consider a smaller format first.

Medium Breed Fit

8. Royal Canin Canine Care Nutrition Medium Digestive Care Adult Dry Dog Food, 17 lb Bag

Prebiotics & Fibre17 lb Bag

Sized and formulated for medium dogs twelve months and older with touchy guts

Royal Canin’s Medium Digestive Care is built around a specific dog: medium breeds, aged 12 months and older, weighing 23–55 pounds, with a sensitive stomach. The formula blends highly digestible proteins, prebiotics, and dietary fibres to promote healthy digestion and support a balanced intestinal flora — with optimal stool quality as the end goal. The chicken-flavoured pellet is also designed to work alongside Royal Canin’s matching wet formulas.

What owners describe is stability after a hard journey. One 8-year-old Whippet who had been dangerously thin after sardine-induced vomiting bounced back on this kibble plus wet food — energy of a much younger dog, no GI issues, healthier stool, shinier coat, and weight near healthy within about a month. A Corgi-shepherd mix who had been vomiting, having diarrhea, and a grumbling stomach since three months of age settled down to being sick only twice on this formula. A small Yorkshire terrier who had thrown up on every other food finally found something that stayed down.

Two practical wrinkles show up in owner notes. Some dogs will only eat the kibble when it is mixed with the matching wet formula, and that wet food carries a strong scent that can linger on a dog’s breath. Cost is the other one: some owners consider it expensive, though many say the effect justifies it.

What makes it different: the nutrition is tailored for medium breeds specifically — not a generic all-size formula — which matters because a 40-pound dog and a 12-pound dog handle a bag of kibble differently.

One thing to plan for: a minority of dogs refuse this kibble unless it is paired with the matching wet food, so budget for mixing or try a small bag first.

The right match: a medium dog (23–55 lb) over a year old who has been through the wringer with stomach trouble.

Wrong fit: toy breeds or large dogs — Royal Canin sizes this formula to medium dogs only.

Prescription Pick

9. Purina Pro Plan Veterinary Diets EN Gastroenteric Dog Food, 16.5 lb Bag

Low FatPrebiotic Formula

Low-fat prescription kibble for the dog whose gut has stopped handling fat

Purina Pro Plan Veterinary Diets EN Gastroenteric is a low-fat prescription formula for dogs who struggle to digest fat. The kibble is highly digestible to promote optimal nutrient absorption, and it carries a select prebiotic for GI microbiome balance plus antioxidant-rich nutrition including a high level of vitamin E to help defend against free radicals. It is one of the more focused formulas in this group — the kind that shows up when a vet has identified a specific fat-processing problem.

The dogs here tend to have a story behind them. One had been on the same food for over seven years and developed a fat intolerance; the owner called this prescription formula easier than cooking for a 165-pound dog and reports the dog is happy and healthy after months. Another dog’s severe pancreatitis was managed on this kibble, with vomiting resolved and calorie control helping an 8-pound weight loss toward an ideal 24 pounds. A 12-year-old Vizsla transitioned to it as a low-fat option and never leaves a bite behind.

The honest notes: it needs a vet’s prescription to order, it runs expensive, and at least a couple of owners have noticed their dogs getting gassy on it. The gas may be a temporary adjustment during transition, or it may signal that a different low-fat formula is a better fit. That is a discussion for your vet, not a reason to abandon it silently.

Where it earns trust

  • Low fat, highly digestible kibble for dogs who cannot process fat well
  • Contains a select prebiotic to support GI microbiome balance
  • Antioxidant-rich nutrition with high vitamin E for immune support

What to weigh

  • Requires a vet prescription to purchase
  • Owners widely call it expensive, though many say it is worth it
  • Some dogs get gassy on it — worth flagging to your vet if it persists past the transition

Best for: dogs with a diagnosed fat-intolerance or pancreatitis issue, working with a vet on a prescription plan.

Not for: healthy dogs or mild, everyday tummy trouble — the off-the-shelf options above fit that case.

Understanding the Specs

Crude Fat Percentage

Crude fat is the share of fat in the food, measured by weight. Lower fat is easier on a dog whose gut is inflamed or whose pancreas is struggling, which is why a formula like Dave’s at 6% crude fat is especially gentle during a flare-up. Everyday kibbles run higher. If your vet has flagged fat intolerance, that number should be your first check.

Highly Digestible Protein

Digestibility is how much of the protein a dog actually absorbs versus how much passes through undigested. The higher the digestibility, the less work the gut has to do, which matters most when a dog is recovering from vomiting or diarrhea. Salmon, chicken, and anchovy are common protein sources in these formulas because they are easy on most dogs — though the right protein depends on what your individual dog tolerates.

Prebiotics And Fibre

Prebiotics are fibres that feed the good bacteria already living in your dog’s gut — they are food for the microbiome, not the dog. Common ones include psyllium husk and proprietary prebiotic blends. Fibre also firms up stool and supports regularity. Some dogs thrive on more fibre; a few do better with less. Adjust only with a vet’s guidance.

Wet vs Dry Formats

Wet food is easier to eat and easier to portion small, which makes it the better choice during an active flare-up or for a dog who has lost appetite. Dry kibble lasts longer, keeps feeding costs down over time, and firms up stool in many dogs. Many owners mix the two — using wet food as a topper for appetite or as the primary food during recovery.

FAQ

Can I feed a bland diet to my dog long term?
Yes, if the formula is complete and balanced. Dave’s Pet Food Bland Diet is AAFCO-compliant for adult maintenance, which means it can serve as the sole meal for a healthy adult dog long term — not just during a flare-up. A short-course bland diet for a puppy or a dog with a diagnosed condition is a different case: talk to your vet before making it the everyday bowl.
What is the difference between a prescription and an off-the-shelf digestive diet?
Prescription formulas such as Royal Canin Gastrointestinal Low Fat and Purina Pro Plan Veterinary Diets EN are formulated for specific medical conditions and require a vet’s authorization to buy. Off-the-shelf limited-ingredient and bland diets like KOHA, Forza10, or Dave’s are designed for milder, ordinary upset stomachs without a diagnosis. If your dog has pancreatitis, fat intolerance, or a chronic GI condition, the prescription route is the safe one.
How long does it take to see a change after switching food?
Give any switch 7–10 days of gradual mixing before you judge it. Some shoppers say faster shifts — a Chihuahua on Hill’s Science Diet Puppy showed appetite and scratching improvements within two days — but that is quick, not typical. If symptoms get worse or new ones appear, stop the switch and call your vet.
Is fish protein better than chicken for a dog with intestinal problems?
Neither is universally better, but the protein your dog reacts to matters most. Chicken is the most common trigger, which is why formulas like Forza10 (anchovy), Purina Pro Plan Sensitive Skin & Stomach (salmon), and Hill’s Science Diet Puppy (salmon) are popular for sensitive dogs. If your dog has done fine on chicken, chicken-based options like Dave’s or Royal Canin Medium Digestive Care are perfectly reasonable.
Can I mix wet and dry food together?
Yes, and many owners do. Royal Canin specifically designs its Gastrointestinal and Medium Digestive Care formulas to be mixed with matching wet food. Hill’s Prescription Diet i/d is also commonly mixed with a matching dry formula, and multiple buyers report dogs eating better when the two are combined. Mixing is especially useful for dogs who are picky or who need extra hydration.
How should I store an opened can of wet dog food?
Refrigerate it. Dave’s Pet Food recommends using an opened can within two to three days, or freezing portions for longer storage. Cover the can or transfer it to a lidded container to keep it from picking up fridge odours. If the food smells off or has changed colour, throw it out — a dog with a sensitive gut is the last one who should be eating food on the edge.
My dog is gassy on a new formula — is that normal?
Some gas during the transition window is common and usually settles once the dog is fully on the new food. If the gas continues well past the transition, or comes with loose stool, vomiting, or appetite loss, that is a signal the formula is not the right fit — flag it to your vet before the next bag. A small share of dogs on Purina Pro Plan EN have reported gas as a persistent issue.
Is grain-free dog food better for intestinal problems?
Not automatically. Many highly digestible foods include grains on purpose — oatmeal is gentle on the digestive system, and Royal Canin’s formulas include dietary fibres to support stool quality. What matters most is that the food is easy to digest, has the right fat level for your dog, and does not include an ingredient your dog reacts to. The vet’s recommendation should always come first.
Do I need a vet’s approval to feed a sensitive stomach formula?
Not for an off-the-shelf sensitive-stomach or limited-ingredient formula like Purina Pro Plan Sensitive Skin & Stomach, Hill’s Science Diet Puppy, or Forza10. You do need a vet’s prescription for a therapeutic diet like Royal Canin Gastrointestinal Low Fat, Hill’s Prescription Diet i/d, or Purina Pro Plan Veterinary Diets EN. When in doubt, ask your vet.
Can I feed a puppy an adult sensitive stomach formula?
No. Puppies have different nutritional needs than adults, and adult formulas are not always safe for growing dogs. Dave’s Bland Diet is explicitly not formulated for puppies. For a puppy with a sensitive stomach, a puppy-specific formula such as Hill’s Science Diet Puppy Sensitive Stomach & Skin is the right starting point.

Final Thoughts: The Verdict

For most homes working through a sensitive-stomach issue, the Hill’s Science Diet Puppy Sensitive Stomach & Skin Dry Dog Food is the pick that gets a puppy eating, digesting, and thriving with fewer complaints from the bowl — and that is why it holds the top spot. If you want a ready-to-serve option for the worst days, keep a can of KOHA Bland Diet on the shelf. For long-term feeding in a chicken-sensitive household, the Purina Pro Plan Sensitive Skin & Stomach is the everyday answer. And if your vet has identified a specific condition like fat intolerance or pancreatitis, the prescription formulas — Royal Canin Gastrointestinal Low Fat and Purina Pro Plan Veterinary Diets EN — are the ones to ask about first, because nothing on this list replaces a conversation with your vet.
