Home / Safety / Toxic Plants / Peach (Tree, Leaves and Pit)
Toxic to dogs. The ASPCA lists peach (tree, leaves and pit) as toxic to dogs. Top tier. Wilted leaf or pit seed eating is an emergency call, and any breathing difficulty, brick red gums or collapse after access to a peach tree means get to a clinic now.
Peach trees fill home orchards, and dogs live under them all summer, cleaning up fallen fruit. The fruit is the decoy: the real hazards are the wilting storm prunings and the pit inside every dropped fruit. The ASPCA lists peach as toxic to dogs, in the Prunus group with plum, apricot and cherry.
A small orchard tree with long, narrow leaves, pink spring blossom and fuzzy fruit. After an incident, the material matters: a wilting branch with leaves turning limp and dark, or a cracked pit exposing the almond like seed. Both sit at ground level after wind, pruning or fruit drop.
The ASPCA names the toxic principle of peach (tree, leaves and pit) as Cyanogenic glycosides, found in some Prunus species. A peach tree keeps its fruit flesh friendly and its other parts armed. Stems, leaves and the seed inside the pit carry cyanogenic glycosides that can release cyanide when chewed, and the ASPCA underlines the wilting point: leaves are particularly toxic in the process of wilting. Cyanide blocks the blood's oxygen work, so the sign list is a breathing and circulation list: brick red mucous membranes, dilated pupils, difficulty breathing, panting and shock.
The clinical signs the ASPCA lists for peach (tree, leaves and pit) are: stems, leaves and seeds contain cyanide, particularly toxic while wilting: brick red mucous membranes, dilated pupils, difficulty breathing, panting and shock. Two seasons, two routes. In storm season, wilted branches are the danger: wilting raises the cyanide availability, so the branch a dog chews the day after it fell is worse than fresh foliage. In fruit season, the route is the pit: a dog crunching dropped peaches can crack the stone and reach the seed. Panting or breathing trouble in a dog with orchard access is never a wait and see picture.
Most dangerous part: Wilted leaves, the most dangerous form named in the entry, and the cracked pit with its seed. A storm broken branch wilting on the ground inside a dog yard is the textbook setup.
The Prunus group warning travels: plum, apricot and cherry trees share this chemistry and have their own entries in the ASPCA list, and this database already carries a wild cherry page. An orchard is therefore a single system to manage, not four separate trees: fence the block, and treat every stone fruit's pit the same way.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 right away, even if your dog looks fine. Some poisons take hours or days to show their worst effects. Do not make your dog vomit unless a veterinarian tells you to, and keep the packaging, a photo, or a sample of what was eaten to show the clinic.
Remove pruned peach branches from dog ground the day they come down, and never toss them into a dog area to wilt. Pick up fallen fruit daily in season, and fence orchard rows away from unsupervised dogs.
For a home orchard in dog territory, the practical swap is management and placement rather than a species: keep stone fruit in a fenced block, and choose any new dog yard tree from species verified as non-toxic on the ASPCA list by scientific name. Whatever you plant next, check it on the toxic plants index approach: confirm the plant on the ASPCA toxic and non-toxic list under its scientific name, Prunus persica is the name to avoid here, before it goes in the ground or on the shelf.
Yes. The ASPCA lists peach (tree, leaves and pit) (Prunus persica) as toxic to dogs. Its toxic principle is Cyanogenic glycosides, found in some Prunus species, and the signs it lists include stems, leaves and seeds contain cyanide, particularly toxic while wilting: brick red mucous membranes, dilated pupils, difficulty breathing, panting and shock.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. Note what part of the plant was eaten and roughly how much, keep any remaining plant material to show the clinic, and do not make your dog vomit unless a veterinarian tells you to.
Wilted leaves, the most dangerous form named in the entry, and the cracked pit with its seed. A storm broken branch wilting on the ground inside a dog yard is the textbook setup.
The ASPCA listing targets stems, leaves and seeds, not the ripe flesh, which is the part people eat. Flesh is still sugary and the pit inside it is both a toxin source and a choking and blockage hazard, so peaches are not a dog treat to offer whole; if your dog ate flesh only, say so when you call.
The ASPCA states it directly: the cyanogenic parts are particularly toxic in the process of wilting. A fallen branch is therefore at its most dangerous in the day or two after it comes down, which is why same day cleanup of storm wood is the core advice on this page.

It is not veterinary advice, and it does not replace your own veterinarian, who knows your dog. If your dog has eaten something toxic, contact your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. A consultation fee may apply on the helplines.
