Australian Shepherds are working dogs with a working dog’s digestion — high energy, sensitive stomach, and a coat that shows every nutritional shortcut. The right bowl keeps that coat thick, the stool firm, and the energy steady through a full day of running. This guide cuts straight to nine dry foods that owners of Aussies, Aussie mixes, and other herding breeds keep coming back to, and it names the single detail that decides each one.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see what each formula leads with, how big the kibble actually is, and which proteins tend to suit a sensitive herding dog best — all so you can pick a bag with confidence the first time. The result is a shortlist you can trust as your dog food for aussies.
Our Picks at a Glance
How To Choose The Best Dog Food For Aussies
An Australian Shepherd sits in the medium-to-large working range, and that shapes almost every choice here. You are feeding a dog that wants to run, sheds a genuine double coat, and often carries a more delicate gut than its athletic build suggests. Get the protein, the fat, and the kibble size right and the rest tends to fall into place.
Protein And Fat Are The Steering Wheel
Protein builds and maintains the muscle an active herding dog burns through, so a recipe with a named meat as its first ingredient is doing real work. Fat is the dial that sets energy and coat condition. Diamond Performance runs 30% protein with 83% of that protein from animal sources, which explains why owners of hardworking dogs gravitate to it. The flip side matters too — Bully Max’s 25/11 formula deliberately drops to 25% protein and 11% fat for dogs that need to hold muscle without gaining weight. Neither number is “better”; they simply suit different dogs.
Watch The Fat Level, Not Just The Protein
Australian Shepherds are prone to slowing down as they age, and a very rich kibble can pack on pounds fast on a dog that now spends more time on the couch than in the field. If your Aussie is a house dog with a couple of daily walks rather than a working ranch dog, a leaner formula like the 25/11 keeps muscle on the frame without the extra fat. If your dog is still running hard, the higher-fat recipes give back the energy.
Kibble Size And Ingredient Count
Aussies tend to be gulpers. A kibble that is too small slides down whole and can cause vomiting or bloat, and a kibble that is too large gets picked at or dropped entirely. Medium-sized kibble suits most Aussies. On ingredients, a limited-ingredient recipe — kangaroo, lamb, or one named protein plus few extras — is the practical route for a dog that scratches, licks its paws, or has loose stools on a standard blend.
What Owners Actually Report
The most common pattern across these brands is a chicken-and-grain swap. Aussies with itching, ear issues, or paw licking often settle down on lamb and kangaroo formulas, while dogs with the toughest guts respond to the highest animal-protein kibble. You will see that pattern repeat through the reviews below.

In‑Depth Reviews
1. Nutrish Salmon Dry Dog Food, 26 lb. Bag (Rachael Ray)
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
A salmon-first bag that feeds a picky heeler for years without a fight.
This food earns the top spot because picky Aussies actually eat it. Salmon is the number-one ingredient, and it comes in a 26-pound bag. Even dogs that usually snub fish tend to lick the bowl clean. The omega fatty acids support a healthy coat, so you may see less shedding and more shine. It works as a daily food for years, not just a short trial. Buyers report a light salmon scent, not the heavy fishy smell that turns dogs away.
It’s veterinarian reviewed and made with no artificial flavors. As one long-term owner put it: “My girl loves it!!! No strong salmon smell at all.” That dog was an Aussie herself, and the owner noted the kibble size suited both a 25-pound and a 60-pound dog. It needs no transition drama for most dogs, which is where a fussy herder either commits or refuses.
The honest catch: this is a mid-tier value pick, not a limited-ingredient formula, so if your Aussie has a known allergy to chicken or grain, look at the kangaroo or lamb options below instead. For a healthy dog with no diagnosed sensitivities, it delivers real salmon nutrition at a fraction of the premium brands’ spend.
What Works in the Bowl
- Salmon as the #1 ingredient, with omega-3 and omega-6 fatty acids for skin and coat health
- Veterinarian reviewed, no artificial flavors
- Kibble size suited both a 25-pound and a 60-pound dog in the same household
- Charitable contribution per bag through The Rachael Ray Foundation
Where It Falls Short
- Not a limited-ingredient recipe, so unsuitable as an elimination diet for an allergic Aussie
- One owner reported weight management issues with a smaller Aussie and had to switch
- Most reviews praise the kibble size, though a few found it too small for a gulper
Best fit for: an adult Aussie with no known food allergies that needs a real-salmon everyday diet that doesn’t break the weekly budget.
Think twice if: your dog has been losing weight on a regular blend and needs a controlled fat level instead.
2. Diamond Performance Puppy, Adult & Senior Dry Dog Food, Chicken, 40lb
Forty pounds of high-protein fuel for a dog that actually works for a living.
For an Aussie on a ranch, a farm, or an agility course, this is the ratio that feeds the work. It’s 30% protein with 83% of that protein from animal sources, and real chicken is the first ingredient. The formula also includes DHA for brain and vision development, glucosamine for joints and mobility, and a blend of probiotics and antioxidants for digestion and immune support.
Here’s the real report from owners — and it tends to mirror what a busy herding dog needs. One long-time buyer noted “High-quality, affordable protein; dog has more energy, muscle, and youthful appearance at 12,” and specifically called out the absence of oatmeal, which had caused loose stools in their dog. Being oatmeal-free is a genuine point of difference for a dog with a sensitive gut, and the 40-pound bag stretches an active household further than most competitors.
The trade-off is honest and worth flagging up front. This is a rich, high-protein, higher-fat formula, and some dog owners mention it caused loose stools in sensitive stomachs when they transitioned too quickly. That’s typical of a performance diet — it rewards a slow transition over a week, not an overnight switch. If your Aussie is a low-activity house companion, a leaner formula will serve the dog better.
The value picture: the cheapest protein per pound in this list, with 40 pounds in a single bag and real chicken as the first ingredient. You are paying farm-feed prices, not boutique-brand prices.
Built for: working Aussies, puppies, and active adults that burn through calories fast and do well on a lean, high-protein diet.
Look elsewhere if: your dog has a sensitive stomach or lives a quiet life — the richness here demands a careful transition and a genuinely active dog.
3. Blue Buffalo Freedom Lamb Adult Grain-Free Dry Dog Food, 24 lb
Turns the paw-licking, rash-prone Aussie into a calm, itch-free dog.
If your Aussie’s issue is skin — scratching, licking, rashes, ear gunk — this is the formula to reach for first. Real lamb is the number-one ingredient, and the grain-free recipe contains no corn, wheat, or soy, plus no chicken or poultry by-product meals. The recipe also includes LifeSource Bits, which are antioxidant-rich pieces added to the kibble for immune support.
The reason it earns a spot this high is the sheer number of owners who report the same pattern: an allergic Aussie or a similar breed gets switched to this lamb formula and the scratching stops. One buyer summed it up elegantly: “Both dogs had kibble issues: Frenchie red eye boogers/paw licking… After 2 yrs raw diet, switched to this lamb kibble—only one both tolerate.” That dog was on a raw diet and still had issues — this formula was the fix.
The real caveat: it’s expensive per pound, and this is a lamb-and-brown-rice formula rather than a full grain-free recipe in the strictest sense for every dog. It’s also not suitable for a dog with a diagnosed fish allergy, since it carries a may-contain-fish allergen notice. But for an Aussie whose whole problem is skin, the swap from chicken to lamb is the single highest-value move you can make.
What earns the label: the lamb-first, grain-free, chicken-free recipe is the direct answer to the single most common complaint in reviewing Aussie and herding dogs — itchy skin.
The follow-up question: if your dog’s issue is digestive rather than skin, the limited-ingredient formulas later in this list are a stronger fit.
Reach for this if: your Aussie scratches, licks its paws, gets rashes, or reacts to chicken and grain-based food.
Skip if: your dog has a genuine fish allergy or you need a true single-protein elimination diet.
4. Bully Max 25/11 High Protein & Low Fat Dry Lamb Dog Food, 15 lb
The formula that holds muscle on a dog that needs to stay lean.
The numbers tell the whole story here — 25% protein and 11% fat is a deliberately lean ratio, aimed at dogs that need to stay muscular without adding weight. It’s chicken-free with real lamb meal as the named protein, and it’s fortified with probiotics and postbiotics for digestion and immunity. For an Aussie whose joints are starting to protest the extra pounds, or a dog coming off a rich formula, this is the controlled-gain option.
If your Aussie is underweight and turns its nose up at food, this recipe can help. Buyers with lean, athletic breeds report the same pattern: a picky dog finally eats and gains condition. One pit bull owner whose dog was losing weight said their dog became “a happy healthy beautiful girl who looks so much stronger and healthier.” Another owner of a 13-year-old pit bull mixed this with regular food and saw weight and energy climb back. The recipe leads with lamb and includes grains like barley and oats. It also has salmon oil, manganese, and DL-methionine (an amino acid) to support joints.
The obvious trade-off: a 15-pound bag costs more per pound than the 26- and 40-pound options, and one owner noted that feeding this exclusively to a low-activity dog led to unwanted weight gain. That’s the flip side of a lean formula — it is still calorie-dense enough to add pounds fast on a couch dog, so it lives up to the label only with a dog that actually moves.
Right call for: seniors, dogs on joint watch, or any Aussie that needs to put on muscle without the extra fat.
Not for you if: you want the cheapest cost-per-pound big bag, or your dog is a coach potato that gains on any rich food.
5. Instinct BeNatural Dry Dog Food, Whole Grain, Lamb & Oatmeal, 24 lb
Lamb and oatmeal that goes down easy on a working Aussie’s gut.
Some Aussies do better with wholesome grains than with a fully grain-free recipe, and this is the pick for those dogs. Grass-fed lamb is the first ingredient, with real animal proteins in the #1 and #2 slots followed by whole grains. Each kibble is coated in freeze-dried raw food, which lifts the flavor and provides a minimally processed edge without extra fuss. It’s free of corn, wheat, soy, by-product meal, brewer’s rice, artificial colors, and preservatives.
This food delivers solid nutrition for the money. One reviewer noted their Aussie and Husky both do well on it, thanks to real animal proteins, no fillers, and no excess additives. Another reviewer wrote, “This kibble is one of the few that has high quality ingredients and low additives.” Buyers also report it clears dermatitis and ear infections in coat-heavy breeds. One owner said it controls dog odor and improves coat shine.
The one real problem owners keep hitting is the packaging. The bag’s seal fails on multiple reports, causing spoilage and waste — a genuine frustration for a 24-pound bag. The paw-fetch problem is real too: this formula is stocked short frequently, so you may need to keep a spare bag on hand. The kibble itself is a bit larger than some dogs prefer, so check whether your Aussie is a chewer or a gulper before committing.
The case for keeping it on the shelf: grass-fed lamb, whole grains, and a raw coating that makes it a real standout for coat condition without pretending to be grain-free.
Wait, hold on: the packaging seal is the recurring gripe — transfer to a sealed container the day it arrives.
Fits best if: your Aussie thrives on whole grains and you want a lamb-first, raw-coated formula for coat and skin.
Not ideal if: your dog needs a strict grain-free recipe or has trouble with larger kibble.
6. Wellness CORE Grain-Free High-Protein Large Breed Adult Dry Dog Food, 26-Pound Bag
Grain-free, chicken-first, and loaded with joint and coat extras in every scoop.
Everything an aging Aussie needs lives in this one bag: 45% high-quality protein ingredients, glucosamine for joints, taurine for heart health, omega fatty acids for skin and coat, and high fiber plus probiotics for digestion. Responsible-sourced chicken leads the recipe and it’s free from corn, wheat, soy, and poultry by-products. It’s made in the USA in the brand’s own facility with non-GMO ingredients.
Owners of large breeds rave about this one. One long-time buyer with a 7.5-year-old Golden Retriever noted the dog “keeps up with puppies, ages gracefully” — soft coat, bright eyes, tons of energy. Another noted the first three ingredients are “Deboned Chicken, Chicken Meal, Turkey Meal,” and praised the formula for replacing multiple supplements. One owner of two elderly German Shepherds reported fewer stomach issues and easier movement.
The honest caveat: the protein level is high enough that a sensitive dog can experience diarrhea during a too-fast transition. It also comes at a premium cost-per-pound — owners note that Subscribe & Save softened the impact, but this isn’t a budget option. It’s the right formula for a dog that needs joint support and a leaner body mass, not a dog on a maintenance diet with no room for extras.
The Big-Breed Argument
- Glucosamine and chondroitin for joint support — critical as Aussies age
- 45% high-quality protein ingredients with chicken, turkey meal, and deboned chicken leading
- Grain-free with no corn, wheat, soy, or poultry by-products
- Includes omega fatty acids, taurine, probiotics, and high fiber all in one kibble
The Watch-Outs
- High protein and fat mean a slow transition is required to avoid diarrhea
- Premium price per pound — best used with Subscribe & Save
- Not a limited-ingredient formula, so not suitable for a true elimination diet
- One owner reported their dog ate too fast and got sick — consider a slow-feed bowl
The pick for you if: your Aussie is at the age where joints need protecting and you want a single kibble to handle coat, digestion, heart, and joints at once.
Pass if: you need the cheapest cost per pound, or your dog is on a strict limited-ingredient protocol.
7. Zignature Kangaroo Limited Ingredient Formula Grain-Free Dry Dog Food, 25-lb
When lamb, chicken, and beef all fail, kangaroo is the protein that finally works.
Kangaroo is not a flavour you try for fun — it’s a novel protein you reach for when every other option has failed. This formula is built on high-quality kangaroo as the first ingredient, with the meat being low in fat and rich in omega-3 fatty acids. It’s a limited-ingredient, hypoallergenic recipe fortified with probiotics, and free of corn, wheat, and grains.
What customers note here is a very specific pattern: dogs with extreme or long-running allergies that nothing else touched finally settle down on this formula. One owner of a dog with IBD said this is the only food the dog tolerates. Another put it plainly: “The only dog food my dog can eat with extreme food allergies.” A German Shepherd owner with a long list of allergy issues reported no allergy symptoms since switching. These are genuine last-resort cases where other brands failed.
Two honest caveats. First, the cost: a 25-pound bag is the second most expensive on this list, and for a large dog it may only last a few weeks. Second, the texture and protein disagree with some dogs — reviewers point out needing to add omega oils to soften the stool, and some dogs simply refuse kangaroo outright. For an allergic Aussie, though, there may be no other workable option.
What turns the corner: a genuinely novel protein paired with a limited-ingredient, grain-free, hypoallergenic recipe — the exact profile that saves dogs who react to chicken, beef, salmon, and lamb.
Worth the spend for: Aussies on an elimination diet, dogs with IBD or severe food allergies, and owners who’ve exhausted the common proteins.
Not the right pick if: your dog is simply a fussy eater, or you want the best cost-per-pound.
8. ACANA Singles Limited Ingredient Dry Dog Food, Lamb & Apple, 22.5 lb
One protein, one grain-free recipe, and a freeze-dried coating dogs hunt for.
When you want a single named protein and nothing else clouding the picture, ACANA Singles delivers. Lamb and lamb liver are the whole protein story here, with 65% animal ingredients and 35% whole fruit, vegetables, and nutrients. It’s grain-free, non-GMO, corn-free, soy-free, and wheat-free, and fortified with a freeze-dried raw coating plus a blend of fiber, prebiotics, and probiotics for gut health. Omega-3 and omega-6 fatty acids round out the skin and coat support.
The feedback from owners is loud and consistent — this is a formula that picky dogs will eat when they’ve walked away from everything else. One buyer of a dog that refused every other grain-free brand noted this was the exception, and another reported it stopped chicken-related allergy vomiting. It’s manufactured in the USA with globally sourced ingredients and adds no antibiotics, artificial flavors, or added sugar.
The honest downside: the smell is strong. Owners describe it as carcass-like, and one specifically noted the kibble resists water and needs 30-60 minutes of hot soaking to soften for a dog that won’t handle hard kibble. It’s also one of the pricier options here. Neither issue is disqualifying — the smell is a byproduct of real organs, and a few minutes of soak solves the texture — but they’re worth knowing before the first bag arrives.
Match made for: a dog with non-specific allergies, a dog that turns down everything else, or an owner committed to a strict grain-free single-protein diet.
Think twice if: you can’t manage a strong smell, or your dog needs soft kibble out of the bag.
9. ORIJEN Amazing Grains WHOLEPREY Dry Dog Food Original Recipe, 22.5 lb
The closest a dry kibble gets to a whole-prey diet, with grains that hold it together.
If you want maximum animal protein without sacrificing whole grains, this is it. Ninety percent of the recipe is animal ingredients including ORIJEN’s WholePrey components — poultry and organs — with the first five ingredients being fresh or raw poultry and fish. It’s 38% protein, grain-inclusive with grains sourced from non-GMO crops, and coated in freeze-dried raw food for a flavour boost that picky eaters respond to instantly. It’s corn-free, potato-free, gluten-free, soy-free, and wheat-free.
Owners of high-energy and working dogs consistently report better stamina, a shinier coat, and improved digestion on this formula. One owner of a 3-year-old shelter poodle mix noted that nine months on Orijen delivered solid waste with minimal residue and zero house accidents after a prior run of loose stool. Another reported it “resolves month-long diarrhea in rescue malamute, firm stool.” The kibble size is generally reported as ideal — not too small for a gulper, not too large for a smaller dog.
Two real catches: price and gut sensitivity. This is among the most expensive options on the list. Even ORIJEN’s own shoppers say that some dogs are too sensitive for the richness, with bloody diarrhea appearing in a subset of dogs during transition. Feed small portions and switch over a week or two. If your Aussie has a sensitive stomach, watch closely. For the dog that can handle it, though, this dry bag offers the richest balance of protein and whole-prey nutrition.
The premium argument: 90% animal ingredients with WholePrey organs and 38% protein means you can feed less per meal and get more nutrition — a real advantage for a working Aussie burning calories all day.
Honest caution: the richness of this diet is the number-one thing owners flag as a problem, so build up slowly and watch the stool.
The one to buy if: you want the highest animal-protein dry diet on this list and your dog has the gut to handle a whole-prey formula.
Look at the Instinct or Diamond instead if: your Aussie is sensitive, the price is a real constraint, or you want a slower-burn everyday feed.
Understanding the Specs
Protein Percentage (And Where It Comes From)
The number on the bag is the share of the food’s weight that is protein — 30% for Diamond Performance, 25% for Bully Max, 38% for ORIJEN. But the source matters just as much as the number. Diamond Performance gets 83% of its protein from animal sources, which is a meaningful distinction: animal protein delivers a more complete amino acid profile than plant protein blends. Aussies are active working dogs, and they use that protein to build muscle and recover — so look for a named meat as the first ingredient, not just a high percentage. The formula matters as much as the number.
Fat Percentage And The Weight-Energy Balance
Fat is where your dog’s energy and coat condition come from, and it’s the single easiest lever to adjust. Bully Max uses 25% protein and just 11% fat, a deliberately lean ratio that helps a dog hold muscle without gaining weight. Wellness CORE uses a higher-fat blend for large breeds that need to maintain a healthy body weight, and Diamond Performance is richer still for dogs in peak work. The rule of thumb for an Aussie: high fat for a working dog, low fat for an aging or house-bound dog that gains weight easily. Neither is better — the right choice depends entirely on your dog’s daily activity.
Limited Ingredient vs Standard Formula
A limited-ingredient formula builds the whole food around one or two proteins and cuts down on everything else. That is the point of Zignature Kangaroo and ACANA Singles Lamb & Apple. If your Aussie scratches, licks its paws, or has loose stools on a standard blend, a limited-ingredient diet is the practical first step. It strips out the suspect proteins and makes it easier to identify what your dog actually reacts to. It’s not a “better” food in general; it’s a better tool for the specific problem of food sensitivity.
Kibble Size And Coat Support
Kibble size matters more for Australian Shepherds than for most dogs because they tend to gulp. Too small and it goes down whole, risking bloat and vomiting; too large and it gets avoided. Medium-sized kibble is the right range for most Aussies. Coat support is the other spec to check: omega-3 and omega-6 fatty acids appear across these brands, from Nutrish to ACANA to ORIJEN, and owners consistently report that those formulas deliver a shinier coat and less shedding. For a double-coated herding breed, that’s not cosmetic — it reflects the dog absorbing the nutrition properly.

Final Thoughts: The Verdict
For most Aussie owners, the best Dog Food For Aussies is the Nutrish Salmon Dry Dog Food — real salmon as the first ingredient with omega fatty acids for coat health, a kibble size that suits both small and large dogs, and a formula built to be fed every day for years. If your dog’s issue is skin and scratching rather than general nutrition, the Blue Buffalo Freedom Lamb is the direct fix. And for a severe or long-running allergy where common proteins have all failed, the Zignature Kangaroo is the one that finally settles the gut. Whatever you choose, feed a slow transition over a week to let your Aussie adjust.
