How much popcorn 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 popcorn it buys if popcorn is the only treat that day. Popcorn has about 387 kcal per 100 g; 1 cup (8 g) is about 31 kcal.
| Dog size | Daily treat budget | Max popcorn a day |
|---|---|---|
| Small (10 lb) | 26 kcal | 7 g (three quarters of cup) |
| Medium (30 lb) | 59 kcal | 15 g (about 2 cup) |
| Large (60 lb) | 100 kcal | 26 g (about 3 cup) |
| Giant (90 lb) | 136 kcal | 35 g (about 4 cup) |

Other grains and bread: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Bread | Small amounts | A small piece of plain bread is safe, but it offers nothing useful. |
| Oatmeal | Small amounts | Yes, plain, cooked with water, as an occasional treat. |
| 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.
