Our objective was to characterize dogs having diabetes mellitus by age, sex, neuter status, body condition score, and body size or breeds. The dataset comprised medical records of 5,343 diabetic or non-diabetic dogs from 102 breeds collected from 1,198 clinics between 2006 and 2013. Dogs were categorized into four body condition score groups. Multilevel logistic regression models were applied to the data. Dogs having diabetes mellitus were characterized by high age, underweight and thin dogs, and also body size or specific breeds such as Toy Poodles (P<0.05), but there was no association with sex (P=0.41) or neuter status (P=0.68). The odds ratio of dogs having DM was 5.6 for underweight and thin dogs compared with ideal dogs (P<0.05). The probability of underweight and thin dogs having diabetes mellitus increased by 16.7% from 1 to 7 years old (P<0.05). The odds ratios of Toy Poodles and Miniature Schnauzers were 3.1 and 1.6, respectively (P<0.05) compared to Other breeds. Additionally, the probability of Toy Poodles having diabetes mellitus increased by 16.4% from 5 to 12 years old (P<0.05), whereas in Shetland Sheepdogs it only increased by 0.4% over the same age range. In conclusion, veterinarians need to consider age, body condition and breed when identifying subclinical diabetic dogs.
