Fresh peach flesh is fine in small amounts with the pit removed. The pit is the problem: it can obstruct a small dog's gut, and the kernel inside contains cyanide-releasing compounds.

More about this food
Peaches split into two very different questions: the flesh and the pit. The ripe flesh is not toxic. The AKC says small amounts of fresh peach, cubed with the stem and pit removed, are a fine source of fiber and vitamin A. The ASPCA, meanwhile, lists peach (Prunus persica, family Rosaceae) as toxic to dogs — but the parts it means are the stems, leaves and seeds, which contain cyanogenic glycosides and are described as particularly toxic in the process of wilting.
What actually happens depends on how the pit was eaten. Pet Poison Helpline explains that the seeds inside peach pits have small amounts of cyanide-containing compounds and enzymes, but because dogs and cats do not thoroughly chew their food, cyanide poisoning after a peach pit ingestion is unlikely. What they do flag is that a swallowed pit may cause a gastrointestinal obstruction in a small breed. So an intact swallowed pit is usually a blockage problem; a pit ground up by a strong-jawed dog is the version that releases cyanide.
When cyanide is released, it moves fast. The Merck Veterinary Manual notes that clinical signs of acute cyanide poisoning generally occur within 15 to 20 minutes to a few hours, and that survival after the onset of clinical signs is rarely more than two hours. Drooling, vomiting, gasping, bright red gums, dilated pupils, labored breathing, collapse and seizures are the signs to know.
If your dog swallowed or chewed a pit, note the dog's weight, how many pits, and the time, then call your veterinarian, an emergency clinic, or the ASPCA Animal Poison Control Center at (888) 426-4435. Repeated vomiting, retching, a guarded belly or no stool passing points to obstruction. Do not induce vomiting at home — a hard pit can do more damage coming back up. This matters most in late summer under a backyard peach tree, where dropped fruit means dozens of pits at ground level. For the flesh, skip canned peaches in syrup and dried peaches, which the AKC flags for excess sugar and added ingredients, and keep all treats within 10% of daily calories.
Frequently asked questions
My dog swallowed a peach pit whole. Is that cyanide poisoning?
Unlikely. Pet Poison Helpline notes that because dogs do not thoroughly chew their food, cyanide poisoning after a peach pit ingestion is improbable. The real concern is obstruction, especially in a small breed, so call your vet now with your dog's weight and the time.
Do I have to peel a peach for my dog?
Washed peach skin is not toxic, but it is fuzzy and tough enough to bother a sensitive stomach, so peeling is the safer default. Either way, remove the stem and pit and cut the flesh into small pieces.
Are canned peaches okay?
No. The AKC advises skipping canned peaches in sugary syrup and dehydrated peaches, which often contain excess sugar and ingredients dogs do not need. A few cubes of ripe fresh peach is the better version.
