Boomslang envenomation in 2 dogs in KwaZulu-Natal, South Africa

Abstract

Although snakebites are frequently seen in small animal practice in South Africa, boomslang (Dispholidus typus) bites are infrequent due to their shy habits. Boomslang venom is a potent procoagulent, causing a consumption coagulopathy and profuse haemorrhage. Boomslang monovalent antivenom is the most effective treatment. This case report describes and discusses 2 small dogs that were presented to a private practice after being bitten by the same boomslang. Boomslang monovalent antivenom administration to both resulted in cessation of bleeding within 45 minutes. One of the dogs developed severe adverse reactions to the antivenom, including vomiting, dyspnoea and nystagmus, which responded well to intravenous cortisone and symptomatic treatment.
