Is Wild Custard Apple toxic to dogs?

Mildly. The ASPCA lists wild custard apple as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. Annona senegalensis contains annonaceous acetogenins in its seeds and bark, as found throughout the genus. Ripe fruit is consumed traditionally across Africa, but the seeds are toxic and should not be ingested by people or animals. Not individually listed by ASPCA; given the known neurotoxic potential of Annona acetogenins for dogs, keep seeds and plant parts away from pets.

Not individually listed by ASPCA; given the known neurotoxic potential of Annona acetogenins for dogs, keep seeds and plant parts away from pets. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to wild custard apple.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Wild Custard Apple is mildly toxic to cats as well. See the full wild custard apple pet-safety guide for both species.
