Yes. Dogs can eat plain apples, but only in small amounts and only after the core and seeds are removed.¹³
Apple flesh is generally safe for dogs, but apple seeds contain cyanogenic compounds and the core can be a choking hazard.¹³ Treats should stay under 10% of daily calories.⁵⁶
What to do if your dog ate apples?
Remove the apple and check what your dog ate: plain slices are usually low risk, but cores and seeds are more concerning.
If your dog ate seeds or swallowed a core, contact your veterinarian for advice, especially if a large amount could be missing.¹³
Offer fresh water and monitor for vomiting, diarrhea, coughing, gagging, or difficulty swallowing.
Seek urgent care if your dog is choking, repeatedly gagging, has trouble breathing, vomits repeatedly, or seems painful or bloated.
For future treats, keep apples as an occasional snack and keep total treats under 10% of daily calories.⁵⁶
