Retrospective study of suspected canine poisoning cases at the Veterinary Teaching Hospital, Federal University of Agriculture, Abeokuta, Nigeria (2009-2019)

Abstract Cases of canine poisoning pose a great challenge to pet owners and veterinarians due to incomplete patient history, late/delayed presentation of pets and the large array of poisonous agents. A ten-year retrospective study on canine poisoning cases presented to the Veterinary Teaching Hospital, Abeokuta, Nigeria was conducted. Descriptive statistics were used to characterize animal signalment, mode, month and year of exposure, severity, treatment and outcome. Associations between explanatory demographic characteristics of patients (age, sex and breed) with poison type and route of exposure were determined using a binary logistic regression model. Fifty-two case records with poisoning history and complete data were reviewed. The study population consisted of twenty males and thirty-two females between two months and five years of age. Poisonous agents that were identified included insecticides/acaricides (83%), cleaning products (2%), rodenticides (4%) and snake venom (6%). Poisoning occurred more in Alsatians, especially during the rainy season. No association between the dog demographics with type of poisoning and route of exposure was observed (p>0.05). There were 4 fatalities and 48 recoveries. This study highlights the heterogeneity of poisonous agents, associated clinical signs, treatment and outcome, and the challenges involved in poison control. Standardized approaches for the collection, assessment, integration of poisoning data and risk management is needed.
