Brodifacoum poisoning in a dog.

A case of brodifacoum poisoning is described in a six-year-old male Kelpie cross working dog. The clinical features were severe exercise intolerance, haemorrhage from the oral and nasal cavities, dyspnoea and pale mucous membranes. Diagnosis was confirmed by demonstrating an abnormally long whole blood clotting time. The dog was treated successfully by administering 1 litre of whole blood intravenously, intramuscular vitamin K1 and a three week course of oral vitamin K3. Experience at the Massey University Small Animal Clinic and Hospital has indicated that poisoning of dogs with the newer long acting anticoagulant rodenticides is becoming more common.
