Yellow: with caution
Yes, but only shelled, unsalted and in small amounts. The ASPCA lists sunflowers as non-toxic to dogs. The problems are the shells, salt and fat.

Why sunflower seeds are marked yellow
According to the American Kennel Club, plain seeds or seeds roasted without salt are fine as an occasional snack. The shells, however, are hard and cannot be digested. They can lodge in the digestive tract and cause an obstruction, and a dog can also choke on them. Salted snack seeds bring a second problem: according to the ASPCA, too much salt can cause intense thirst, vomiting, diarrhoea, trembling and, in extreme cases, seizures.
What to watch for
- Shelled only: Keep seeds still in their shells for yourself; do not share them with your dog.
- Without salt: No salted or seasoned snack seeds.
- Watch the fat: Seeds are high in fat. The AKC recommends avoiding them altogether if your dog is prone to pancreatitis or has a sensitive stomach.
- Secure bird food: Position feeders and store bags of bird seed where your dog cannot reach them.
- Count them in: A few seeds quickly add up to a small meal’s worth of energy.
What if your dog has eaten seeds with shells?
If your dog has eaten seeds with their shells, perhaps from a bag of bird food, watch for vomiting, abdominal pain, loss of appetite and an inability to pass stools. Call your vet if these occur. After a lot of salted seeds, offer water and ask your vet for advice too, especially with small dogs.
If you suspect poisoning, take your dog to a vet or an emergency veterinary service immediately.
