Can dogs eat
Sunflower Seeds?
In moderation
Yes, in small amounts. Healthy adult dogs can have a few plain, shelled, unsalted sunflower seeds as an occasional treat. Shells and salted or flavored seeds are the problem.
Why it’s fine in small amounts
Sunflower seeds are not toxic to dogs. PetMD considers plain seeds fine for healthy adults once the shells are off and as long as no salt was added, and the AKC calls plain seeds a relatively healthy occasional treat. They contain vitamin E, B vitamins, selenium, copper and manganese, plus fatty acids that the AKC says may support skin and coat, although it notes that research on this comes from supplements. A dog on a complete diet should already get what it needs.
Watch the fat. Seeds are calorie-dense, and PetMD warns they can contribute to weight gain or pancreatitis, so dogs with a history of pancreatitis should avoid them. The AKC and PetMD both say to remove the shells, which are hard, do not digest and can cause choking or a blockage. Salted or flavored seeds are a bigger worry: the AKC says they can cause salt toxicosis, with tremors, weakness and gastroenteritis.
The sunflower plant itself is not toxic, according to PetMD, though a dog that eats a lot of it may get a mild stomach upset. The seasonings on flavored seed packets are the bigger concern.
Benefits
- Source of vitamin E, B vitamins, selenium, copper and manganese
- Fatty acids that may support skin and coat health
- Small, crunchy and easy to sprinkle over food or use in puzzle toys
Risks
- Shells are a choking hazard, hard to digest and can cause blockages
- High in fat, which can add weight and trigger pancreatitis in susceptible dogs
- Salted, flavored or oil-roasted seeds can cause salt toxicosis and stomach upset
- Sunflower butter with xylitol or added ingredients is unsafe
How to serve it safely
Choose plain, shelled, unsalted seeds, either raw or dry-toasted. Start with one or two seeds and watch for a few hours. You can sprinkle seeds over food, mix them into a puzzle toy or fold them into homemade treats.
The AKC suggests about 10 to 20 seeds a week for a small dog and about 20 to 40 for a large dog. PetMD measures it in spoonfuls instead, from about half a teaspoon for a dog under 10 lb (4.5 kg) to 2 tablespoons for a dog over 90 lb (41 kg), two or three times a week. For sunflower butter, PetMD says to choose a plain, xylitol-free kind and give only small spoonfuls. Treats should stay under about 10% of daily calories.

If your dog already ate it
A few plain shelled seeds will most likely do no harm. If your dog swallowed a lot of shells, watch for vomiting, lethargy, loss of appetite or belly pain, and call your vet if you see them, since shells can cause a blockage.
If your dog ate a big helping of salted or flavored seeds, call your vet, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply). Call right away for tremors, weakness or repeated vomiting. If the product contained xylitol, treat it as an emergency. Do not make your dog vomit at home.
