Is White Sapote toxic to dogs?

Yes — white sapote is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. The seeds, bark, and leaves of Casimiroa edulis contain sedative alkaloids (casimiroedine, casimiroin) that are toxic to humans, dogs, and cats — seeds are considered fatally toxic if consumed raw by animals or in quantity by people. The ripe fruit flesh is edible but should be kept out of reach of pets. ASPCA does not individually list this species; veterinary consultation is advised if pets ingest any part other than ripe flesh.

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 white sapote.

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: White Sapote is toxic to cats as well. See the full white sapote pet-safety guide for both species.
