Are apple seeds poisonous to dogs?

Apple seeds contain amygdalin, which releases tiny amounts of cyanide when chewed. A few seeds swallowed once are very unlikely to poison a dog, but there's no reason to allow it — core the apple and the question disappears.

Can dogs eat apple skin?

Yes, the peel is safe and adds fiber. Wash the apple first, and consider peeling for dogs with sensitive stomachs since the extra fiber can loosen stool.

Can puppies eat apples?

Yes — small, thin slices without core or seeds. Introduce any new food gradually and watch the stool for a day.

Can diabetic dogs eat apples?

Apples contain natural sugar, so ask your vet first. For most diabetic dogs a small slice is acceptable occasionally, but low-sugar vegetables are the safer default treat.

Why apples are a good treat for dogs

Apple flesh is low in fat and protein and high in fiber, vitamin A and vitamin C, which makes it a solid treat even for senior dogs on restricted diets. The crunch also helps a bit with teeth cleaning, and most dogs genuinely like the sweetness.

Prep matters: core and seeds out

Two parts of the apple don’t belong in your dog:

The core is a choking and gut-obstruction hazard, especially for enthusiastic gulpers.
The seeds contain amygdalin, which releases small amounts of cyanide when chewed. Swallowing a few seeds once is very unlikely to cause poisoning — the amounts are tiny — but coring the apple removes the risk entirely.

Wash the skin, slice the apple, and size the pieces to your dog: thin slices for small dogs, wedges for large ones.

How much apple can a dog have?

Treats of all kinds should stay under about 10% of daily calories. In practice that’s a few slices for a medium dog. Too much apple — like too much of any fruit — can cause loose stool from the fiber and sugar.

When to check with your vet

Diabetic dogs and dogs on prescription diets should get apples only with a vet’s OK. If your dog swallowed a whole core, watch for vomiting, appetite loss or straining and call your vet if they appear.
