CANINE DIET AND OBESITY

Study design: internet survey of Hungarian companion dogs.
Outcome studied: 1448 responses, dogs were of various breeds, ages (mean = 4.2, SD = 3.09), sex and reproductive statuses (males: n = 662, females: n = 786, from which neutered males: n = 305,
neutered females: n = 517, respectively). Owners were questioned about the body condition of their dogs and social factors that affect BCS (keeping conditions, joint activity, feeding, providing treats, and behavioural problems).
the feeding of commercial dog food (kibble) and/or leftovers of human meals coincided with being overweight
dogs that were fed (fully, or at least partly) with raw food were less likely overweight.
dogs that were never fed with commercial dog food were less likely to be overweight than dogs that were fed commercial dog food with any frequency
dogs that were never given human food (mainly leftovers) were less likely to be overweight than dogs that were fed human food with any frequency
dogs that never ate raw food were more likely to be overweight than dogs that were fed raw food with any frequency
dogs that were fed human food but also ate raw with any frequency were less likely to be overweight than dogs that were fed human food but not raw
there was no significant difference between the body condition of dogs eating both human food and raw and dogs that never ate human food
Strengths of this study: large sample size, participation was voluntary, with no financial incentive given.
Limitations: not a representative sample, possible responder bias. Obesity was reported from the owner and their vet’s evaluation, however this was not verified so obesity could be under or misreported.
