Plain-English summary
A survey of 204 dogs from five different breeds looked into thyroid function and infertility. The study found that only a small percentage of Dogue de Bordeaux (4.5%) and Leonbergers (2.4%) had hypothyroidism, but these dogs did not show any reproductive issues. Interestingly, 70% of male Dogue de Bordeaux had low thyroid hormone levels, while other breeds tested had normal levels. However, there was no significant difference in thyroid hormone levels between dogs that were fertile and those that were not.

Abstract
In our study, a clinical and reproductive examination was undertaken in 204 dogs of five different breeds. Thyroxine and thyroid-stimulating hormone plasma concentrations were assayed in order to assess the real incidence of hypothyroidism associated with reproductive disease. Among these animals, only two breeds were affected by hypothyroidism (4.5% of the Dogue de Bordeaux and 2.4% of the Leonbergers). Moreover, these animals did not suffer from any reproductive disease. Our study showed also that 70% of the male Dogue de Bordeaux were hypothyroxinemic compared with Great Danes, English Mastiff and Leonbergers whose male population was 100% normothyroidic. We found the same tendency in bitches. In our data, there was no difference in thyroxin plasma concentrations between normo- and hypofertile dogs, but our results were not statistically significant.
