Can dogs eat apple core?

Avoid
Core is a choking/obstruction risk and may include seeds.

No. Dogs should not be given the apple core. Even if the fruit itself is fine, the core is the part most likely to create unnecessary trouble because it is hard, awkward to chew, and may still contain seeds.

If a dog grabbed the core by accident, that is more of a choking or obstruction question than a nutrition question. It is much safer to remove it completely before serving any apple.

Why apple core is a bad choice for dogs

The core is tougher than the flesh and may be difficult to chew or pass. It also often comes with leftover seeds, which adds another reason not to feed it.

What to do if your dog eats apple core

1. Remove any remaining apple pieces.

2. Monitor for gagging, vomiting, belly pain, or trouble passing stool.

3. Contact your veterinarian if your dog swallowed a large chunk or seems uncomfortable.

4. Serve only cored apple pieces in the future.

Signs to watch for

For dogs, the apple core should always be discarded.
