Is Mangetout Pea toxic to dogs?

Mildly. The ASPCA lists mangetout pea 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. Pisum sativum is not individually listed by the ASPCA, so status is uncertain; treat with caution and verify with a vet. The edible pods and peas are a common human food, but like other legumes raw mature seeds contain lectins and are best cooked; do not assume safety for pets. Note that ornamental sweet pea (Lathyrus) is a different, toxic plant and should never be confused with edible peas.

Note that ornamental sweet pea (Lathyrus) is a different, toxic plant and should never be confused with edible peas. 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 mangetout pea.

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: Mangetout Pea is mildly toxic to cats as well. See the full mangetout pea pet-safety guide for both species.
