Is curled dock safe for cats and dogs?
Toxic — the ASPCA lists curled dock as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The ASPCA lists dock (Rumex spp.) as toxic to cats, dogs, and horses. The toxic principles are soluble calcium oxalates. Clinical signs include kidney failure (rare but reported), muscle tremors, hypersalivation, weakness, and gastrointestinal upset. Soluble oxalates bind serum calcium rapidly, causing hypocalcaemia that impairs cell membrane function. Contact a veterinarian immediately if ingestion is suspected.
