Is Argyroderma testiculare toxic to dogs?

Mildly. The ASPCA lists argyroderma testiculare 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. Argyroderma is not individually listed on the ASPCA Toxic and Non-Toxic Plants database. Its family, Aizoaceae, is mixed: the ASPCA lists Lithops ("Living Stones") as non-toxic but lists the related mesemb Dinteranthus as toxic to cats and dogs. Because this genus is unconfirmed, treat it with caution, keep it out of reach, and verify with a vet before assuming it is pet-safe.

Because this genus is unconfirmed, treat it with caution, keep it out of reach, and verify with a vet before assuming it is pet-safe. 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 argyroderma testiculare.

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 in the US, or Animal PoisonLine on 01202 509 000 in the UK 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: Argyroderma testiculare is mildly toxic to cats as well. See the full argyroderma testiculare pet-safety guide for both species.
