Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Apple slices (without seeds, core, or stem) are a healthy, low-calorie treat for dogs. They provide vitamins A and C, and fibre. Apple seeds contain amygdalin, which releases cyanide when chewed — while a few seeds are unlikely to cause harm, it's best to always remove them. The core can also be a choking hazard. Avoid feeding your dog apple-flavoured products or apple pie, which contain added sugar and spices.
What You Should Know
While apples is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
