Is Apple safe for dogs?
Malus sylvestris
Also known as Malus domestica
The apple tree is a deciduous fruit-bearing plant known for its edible fruit, though the seeds and foliage contain cyanogenic glycosides that can be harmful if ingested in large quantities. While the fruit flesh is generally safe, the plant parts containing amygdalin pose a risk to pets.

What this means for your dog
Dogs are the more common worry with apple plants because they're more likely to crunch through seeds or strip wilting leaves off a fallen branch. ASPCA lists Malus sylvestris as toxic to dogs — the cyanogenic glycosides in the stems, leaves, and seeds release cyanide when chewed, with the wilting process making the foliage especially dangerous.
What to watch for
ASPCA-listed signs in dogs are brick-red mucous membranes, dilated pupils, difficulty breathing, panting, and shock. Drooling and vomiting often appear first. A dog that swallowed a few whole, intact seeds is usually fine; a dog that crunched a mouthful of seeds or stripped wilting leaves is a different story.
Time window
Onset depends on the amount chewed and how thoroughly the seeds were crushed. Cyanide acts rapidly once released, but ASPCA does not publish dog-specific time-to-onset numbers; specific timing is not well documented for canine apple ingestion.
When to call the vet
Call your veterinarian or ASPCA Animal Poison Control (888-426-4435) immediately if you see panting, labored breathing, or red or bluish gums. Call right away — before symptoms — for any chewed-seed exposure in a small dog, or any meaningful ingestion of wilting leaves or stems.
First aid at home
Per Pet Poison Helpline general poisoning guidance: remove your dog from the plant, do not give home antidotes, and do not induce vomiting unless a vet or poison control directs you. Then call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661).
