RESUMO
OBJECTIVES: The cost of feeding a purpose-formulated weight loss diet may deter owners of obese dogs from proceeding with a weight loss programme. The current study aimed to compare average food costs during weight loss with those before weight loss. MATERIALS AND METHODS: Average daily food costs, for before and during weight loss, were calculated in 22 obese dogs that had successfully completed weight management. RESULTS: The median food cost before weight loss was £0 · 52/day (£0 · 24-3 · 31/day), for main meal only, and £0 · 64/day (£0 · 26-3 · 31/day) for main meal and additional food (table scraps and treats). The median food cost during weight loss was £0 · 90/day (£0 · 26-1 · 36/day), and no additional food was given. The average daily feeding costs during weight loss did not differ from pre-weight-loss costs, either with (P = 0 · 425) or without (P = 0 · 222) the additional food included. CLINICAL SIGNIFICANCE: Knowledge that average diet costs do not significantly differ from food costs prior to weight loss may help veterinarians to persuade owners to enrol obese dogs in a weight management programme.
