Yes — plain apple flesh is safe for most healthy dogs as an occasional treat. Remove the core and all seeds, cut into slices matched to your dog's size, and keep portions small.

Are apple seeds poisonous to dogs?

Apple seeds contain amygdalin, which releases cyanide when chewed. A stray swallowed seed is unlikely to poison a dog, but there is no reason to take the risk — always remove the core and seeds.

Can dogs eat apple skin and cores?

Skin is fine for most dogs when the apple is washed. Cores are not — they are tough to chew, a choking hazard, and carry the seeds. Core the apple before sharing.

Can puppies eat apples?

Puppies over weaning age can try a small piece of cored, seedless apple. Introduce gradually and watch for loose stools — fruit should never replace balanced puppy food.

How much apple can a dog eat?

A few slices is plenty for a small dog; larger dogs can have a little more, occasionally. Too much apple means too much sugar and fibre — expect wind or diarrhoea.

Can Dogs Eat Apples UK?

Quick answer

Yes — dogs can eat apple flesh in moderation. Remove the core and every seed: apple seeds contain amygdalin, which releases cyanide when chewed, and the core is a choking hazard. Serve plain slices as an occasional treat — too much apple can cause an upset stomach from sugar and fibre.

Key takeaways

Dogs can eat apple flesh and skin in moderation — always remove the core and seeds first.
Apple seeds contain amygdalin, a cyanogenic compound, and the core is a choking hazard.
Too much apple can cause an upset stomach — keep portions small, especially for small dogs.

Can dogs eat apples?

Yes — according to the PDSA and Blue Cross, plain apple flesh is a safe occasional treat for most healthy UK dogs. Apples are crunchy, low in fat, and many dogs enjoy them as an alternative to shop-bought treats.

Apples are a treat, not a meal. Complete dog food provides balanced nutrition; fruit should make up only a small part of your dog's daily diet.

Which parts of an apple are safe?

Part of the apple	Safe?	Notes
Flesh	Yes, in moderation	Plain only — no sugar, spice or dips
Skin	Yes, washed	Extra fibre; peel for sensitive stomachs
Core	No	Tough and hard to chew — choking hazard
Seeds	No	Contain amygdalin — a cyanogenic compound

One swallowed seed is unlikely to harm a dog, but the seeds-and-core habit is not worth the risk. Core every apple before sharing.

Why remove the seeds?

Apple seeds contain amygdalin, a compound that releases cyanide when seeds are chewed and digested. The quantities are small, but seeds offer no benefit and there is no safe reason to feed them — always remove the core and seeds first.

How to serve apples to your dog

Wash the apple
Remove the core and all seeds
Cut into slices or chunks matched to your dog's size — a few slices for a small dog
Serve plain — no toffee, caramel, sugar or spiced bakes, and check any dip ingredients first

Frozen apple slices make a crunchy summer treat — supervise, just as you would with watermelon.

How much apple is too much?

Too much apple delivers too much sugar and fibre — the usual result is wind, soft stools or diarrhoea. Dogs with obesity, diabetes or sensitive stomachs need vet-approved treat plans before fruit of any kind.

Apples are a world away from grapes and raisins, which are toxic to dogs with no safe dose — see what fruit can dogs eat for the full safe-and-toxic list.

When to call your vet

Phone your vet if your dog:

Ate a large quantity of cores or seeds and seems unwell
Chokes on a piece of apple or core — gagging, pawing at the mouth, distress
Vomits repeatedly or has diarrhoea that does not settle after eating apple
Has diabetes or another long-term condition and you are unsure about fruit treats
