Objective
To identify risk factors for canine lymphoma in dogs from New South Wales, Australia, and to compare factors affecting remission duration.
Methods
Client‐owned dogs diagnosed with lymphoma presented to the University Veterinary Teaching Hospital (UVTH), University of Sydney, between 2001 and 2009 (n = 134) were compared with a control population of dogs seen in that period of time with a diagnosis other than lymphoma to evaluate association of explanatory variables (breed, age and sex) with the outcome (case or control status).
Results
The Australian Cattle Dog (odds ratio (OR) = 4.71; 95% confidence interval (Cl) 2.31–9.62; P < 0.001), Doberman (OR = 7.64; 95% Cl 2.87–20.34; P = 0.001) and Rottweiler (OR = 4.52; 95% Cl 2.09–9.73; P = 0.001) had increased odds of lymphoma among dogs attending the UVTH compared with crossbreds. The results suggested that the Border Collie (OR = 3.38; 95% Cl 1.52–7.53; P = 0.008) and Boxer (OR = 3.85; 95% Cl 1.65–8.95; P = 0.006) also have increased odds of lymphoma among the pure‐breed dogs attending the UVTH when compared with crossbred dogs.
Conclusions
The results of this study confirmed a breed predilection for lymphoma in dogs, with the Australian Cattle Dog and Doberman having increased odds of lymphoma.
