Plain-English summary
A study in Grenada found that 102 out of 7180 dogs were diagnosed with canine transmissible venereal tumor (CTVT), a type of cancer affecting dogs. The research showed that Grenadian pothounds and mixed-breed dogs were more likely to develop this tumor compared to purebreds, and neutered dogs had a higher risk than those that were not neutered. Age and gender did not seem to play a significant role in the risk of developing CTVT. This information can help pet owners understand the risks associated with certain breeds and the impact of neutering on their dogs' health.

Abstract
BACKGROUND: Canine transmissible venereal tumour (CTVT) is a naturally occurring neoplasia affecting dogs worldwide. Previous CTVT studies in Grenada were limited to case records of dogs with neoplastic conditions at a veterinary diagnostic laboratory. OBJECTIVES: The present retrospective study aimed to determine the occurrence and risk factors of CTVT in a wider population of owned dogs presented to a university-affiliated veterinary hospital between 2008 and 2018. METHODS: Data on the age, breed, gender, and gonadectomy status were retrieved from an electronic database and analyzed using logistic regression. RESULTS: Of the 7180 dogs presented during the period, 102 dogs (1.4%) were diagnosed with CTVT. A higher predisposition was observed in Grenadian pothounds (odds ratio [OR] = 22.8, 95% confidence interval [CI] 10.3-50.4; p < 0.001) and mixed-breed dogs (OR = 9.2, 95% CI 4.1-20.7; p < 0.001) in comparison to the purebreds. Neutered dogs (OR = 2.2, 95% CI 1.4-3.3; p < 0.001) were at an increased risk of CTVT than intact dogs. Age and gender were not identified as significant risk factors. CONCLUSIONS: The percentage of dogs with CTVT in this study represents a crude estimate of the CTVT prevalence in the owned dog population in Grenada. Further studies including both owned and free-roaming dogs are required for a more accurate estimation of the CTVT prevalence in the region. Our results indicate that breed and gonadectomy status are significant risk factors for the occurrence of CTVT in Grenada.
