ABSTRACT Raw feeding is becoming an increasingly popular dietary choice for dogs; however, raw diets can have several negative health implications. This article aims to explore the negative effects of a raw diet on canine health and considers the role of the veterinary nurse (VN) in minimising these effects. Through a systematic literature review, eight papers relating to the research topic were identified and critiqued by the authors, allowing conclusions to be drawn on the negative effects of a raw diet. Bacterial and parasitic infections and nutritional imbalances were identified as the most common negative effects of a raw diet. The most commonly identified bacteria were Escherichia coli and Salmonella, with Sarcocystis and Toxoplasma gondii presenting as common parasites, as well as the uncommon coccidian parasite Hammondia heydorni. Musculoskeletal issues were identified as consequences of a nutritionally imbalanced raw diet. Inappropriate raw diets clearly have negative effects on canine health; however, there is a need for further research in several areas in order to more completely understand the issues. Through further research, and VNs’ contributions to the promotion of healthy raw diets, animal health and welfare can be improved.
