Why
Plain bread is just carbohydrate and calories. The AKC suggests avoiding it altogether, and raw yeast dough is a real danger.
How to serve bread
- If you do share, a small piece of plain white or wheat bread.
Watch out for
- Never raisin, garlic or onion bread.
- Raw bread dough can expand in the stomach and produce alcohol: an emergency.
How much bread can a dog eat?
Treats of every kind should stay under 10% of a dog's daily calories, says the World Small Animal Veterinary Association. Here is that daily treat budget by size, and how much bread it buys if bread is the only treat that day. Bread has about 266 kcal per 100 g; 1 slice (29 g) is about 77 kcal.
| Dog size | Daily treat budget | Max bread a day |
|---|---|---|
| Small (10 lb) | 26 kcal | 10 g (a third of slice) |
| Medium (30 lb) | 59 kcal | 22 g (two thirds of slice) |
| Large (60 lb) | 100 kcal | 38 g (about one and a half slice) |
| Giant (90 lb) | 136 kcal | 51 g (about 2 slice) |
Less is better for small, overweight or diabetic dogs. Work out your own dog's numbers with the dog food calculator. Calories: USDA FoodData Central, Bread, white, commercially prepared (includes soft bread crumbs).
Other grains and bread: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Oatmeal | Small amounts | Yes, plain, cooked with water, as an occasional treat. |
| Popcorn | Small amounts | Yes, plain air-popped popcorn with no butter, salt or unpopped kernels. |
| Raw bread dough | Toxic | No. Raw yeast dough can expand in the stomach and produce alcohol. |
| Quinoa | Safe | Yes. Plain cooked quinoa is safe and appears in some dog foods. |
| Rice | Safe | Yes. Plain cooked white rice is easy to digest and often used for upset stomachs. |
Rules for any new food
- Plain is the rule: no salt, butter, oil, onion, garlic, sugar or sweeteners. Most of the danger in human food comes from what is added to it.
- Keep all treats under 10% of your dog's daily calories (WSAVA). The rest should come from a complete dog food.
- Check labels for xylitol, raisins, chocolate and macadamia nuts, which turn up in baked goods, snacks and spreads.
- If your dog has a health condition, such as diabetes, pancreatitis or kidney disease, ask your vet before adding any new food.
