Is Hosui Asian pear toxic to dogs?

Mildly. The ASPCA lists hosui asian pear 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. Pyrus pyrifolia seeds contain amygdalin (cyanogenic glycoside), as do other Rosaceae with stone-fruit-type seeds. ASPCA does not individually list Pyrus pyrifolia, but cyanogenic Rosaceae seeds are considered toxic to dogs, cats, and horses. Ripe fruit flesh is safe for human consumption. Prevent pets from ingesting seeds, leaves, or bark.

Prevent pets from ingesting seeds, leaves, or bark. 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 hosui asian pear.

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: Hosui Asian pear is mildly toxic to cats as well. See the full hosui asian pear pet-safety guide for both species.
