Plastic explosive poisoning in dogs

A dog suspected of having ingested minute quantities of plastic explosive type 4 (PE4 containing cyclonite) was presented with congested mucous membranes, a fever, an increased pulse rate, hyperventilation, hypersensitivity and mild convulsions. Experimental poisoning of a dog confirmed the neurotoxic properties of PE4 and proved to be fatal at 14 mg kg-1 within 18 h after ingestion. The clinical signs and post mortem findings closely resembled strychnine poisoning in dogs.
