Bottom line: Yes, dogs can eat apples. Apples are a low-calorie, vitamin-rich treat that can freshen breath and provide fibre. Always remove the seeds and core first, apple seeds contain amygdalin, which releases cyanide when chewed. A few seeds are harmless, but it is best to avoid them entirely.
| Situation | Suggested action |
|---|---|
| Dog ate a few apple slices (no seeds) | No action needed, apples are safe |
| Dog ate a whole apple including seeds | Monitor; a few seeds are not harmful, but call vet if large amounts eaten |
| Dog ate apple cores regularly | Stop, core and seeds are the risky part |
| Dog ate apple pie or apple crumble | Check for xylitol or nutmeg; call vet if concerned |
Are apples safe for dogs?
Yes. Apples are a popular, healthy treat for dogs and are a good alternative to shop-bought treats that are high in fat or salt. They offer:
- Vitamin A and C, support the immune system and skin health
- Fibre, aids digestion
- Low calories, useful for weight management (see our guide on is my pet overweight)
- Crunchy texture, can help clean teeth and freshen breath
Why remove the seeds and core?
Apple seeds contain amygdalin, a compound that releases cyanide when crushed and digested. A dog would need to eat a very large quantity of chewed seeds to become unwell, so a few accidentally swallowed seeds are not an emergency, but it is sensible to remove the core and seeds every time.
The tough, fibrous core can also be a choking hazard or cause a blockage, especially in small dogs.
How much apple can a dog eat?
Treats should make up no more than 10% of your dog's daily calories. A few slices a day is a reasonable portion for most dogs. Cut slices into small pieces for toy breeds to avoid choking.
How to feed apples safely
- Wash the apple to remove pesticide residue
- Remove the core and all seeds
- Cut into bite-sized pieces
- Offer fresh or frozen slices as a cooling treat
- Avoid dried apple with added sugar, apple crisps with seasoning, and apple baked goods (apple pie, crumble) which may contain sugar, butter, nutmeg, or xylitol
Nutmeg is toxic to dogs and is sometimes used in apple-based desserts, so keep all spiced or sweetened apple products away from your dog.
Can dogs with diabetes eat apples?
Apples contain natural sugar. A small slice occasionally may be fine, but check with your vet before feeding apples to a diabetic dog, as the sugar content can affect blood glucose control.
When to call the vet
Call your veterinarian if your dog:
- Eats a large number of apple seeds and seems unwell
- Swallows a whole apple core and shows signs of blockage (vomiting, not eating, abdominal pain)
- Eats apple pie or baked apple and you are unsure whether it contained xylitol or nutmeg
- Develops vomiting, diarrhoea, or signs of an allergic reaction after eating apple
