Is Silver Crown toxic to dogs?

Yes — silver crown is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Cotyledon species contain bufadienolide cardiac glycosides (including orbicusides and cotyledontoxin) that cause cotyledonosis — a serious poisoning syndrome in livestock involving cardiac arrhythmia, muscle tremors, and paralysis. Cotyledon orbiculata is documented as toxic to dogs via cardiac glycoside ingestion (canine poisoning case reports exist). Cotyledon undulata shares the same genus and toxic compound class. Keep away from dogs, cats, horses, livestock, and children.

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 silver crown.

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: Silver Crown is toxic to cats as well. See the full silver crown pet-safety guide for both species.
