Plain-English summary
A study found that bone tumors were diagnosed in 764 dogs under 10 years old in Sweden, with certain breeds like the Irish wolfhound, St. Bernard, and leonberger being at higher risk. The overall incidence was about 5.5 cases per 10,000 dogs each year. Unfortunately, the average survival time after diagnosis was only 56 days for those that lived at least one day post-diagnosis. Interestingly, female dogs had a lower risk of developing bone tumors compared to males.

Abstract
The objectives of this study were to describe the incidence of, survival until, and survival after the diagnosis of canine bone tumors by breed, sex, age, and geographic location of residence. Dogs under 10 y old and insured by a Swedish insurance company between 1995 and 2002 were studied. In total, 764 dogs had claims for bone tumors, and the incidence rate was 5.5 cases per 10 000 dog-years at risk (DYAR). At ages 6, 8, and 10 y, the proportions of dogs with bone tumors were 0.13%, 0.30%, and 0.64%. The top 3 breeds at risk were Irish wolfhound, St. Bernard, and leonberger (incidence rates 99, 78, and 53 cases per 10 000 DYAR, respectively). Median survival time after diagnosis was 56 d in the 419 dogs that survived > or = 1 d. With a Cox regression model controlling for breed and age, females were shown to be at decreased risk of bone tumors, with a hazard ratio of 0.71 (99% confidence interval 0.58 to 0.87).
