Dog biscuits are safe for dogs only when they are dog-specific, fed in moderation (under 10% of daily calories), and free from toxic ingredients like xylitol or chocolate.
For the full breakdown, see our best Dog Biscuits for Teeth guide.
Whether dog biscuits are “good” for your dog depends entirely on which biscuits and how many. The right dog-formulated biscuit used as an occasional treat is fine for most healthy dogs. The wrong biscuit — especially any human biscuit or one loaded with sugar, salt, or risky additives — can cause real harm. Here is what you need to know to make the call for your dog.
Dog Biscuits vs. Human Biscuits: The Key Distinction
The biggest mistake dog owners make is assuming human biscuits are safe for dogs. They are not. Human biscuits are typically high in sugar, fat, and salt, and may contain ingredients that are toxic to dogs — including xylitol (a sweetener highly toxic even in small amounts), chocolate, raisins, nutmeg, or macadamia nuts. Never feed your dog a human biscuit.
Dog-formulated biscuits, on the other hand, are baked specifically for canine digestion. These are designed to be digestible and to avoid the common toxins that appear in human baked goods. But “dog biscuit” on the label does not automatically mean healthy — you still need to read the ingredient list.
What to Look For (and Avoid) in Dog Biscuits
When choosing a dog biscuit, the ingredient list tells the real story.
| Prefer These Ingredients | Avoid These Ingredients |
|---|---|
| Real meat (chicken, beef, salmon) as first ingredient | Xylitol or artificial sweeteners |
| Oat flour, brown rice, or whole grains | Corn or wheat gluten |
| Dog-safe produce: pumpkin, apples, carrots, sweet potato | Propylene glycol (PG), BHA, BHT, ethoxyquin |
| Natural preservatives (vitamin E, vitamin C) | Artificial food dyes (Yellow 5, Red 40, etc.) |
| Omega-3s or added fiber | Rendered fats, unnamed “animal by-products” |
How Many Dog Biscuits Are Too Many?
The 10% rule is the standard across veterinary nutrition: treats of all kinds should make up no more than 10% of your dog’s daily caloric intake. For a 50-pound dog eating about 1,000 calories per day, that means treats should provide at most 100 calories. Overfeeding biscuits leads to weight gain, digestive upset, and can crowd out the balanced nutrition your dog needs from their regular food.
Dogs with existing health conditions need extra caution. Dogs with diabetes, kidney disease, or food allergies should only receive treats approved by a veterinarian.
