Is Cryptorchidism More Common In Border Collie


Cryptorchidism is a condition in which one or both testicles fail to descend into the scrotum. This is a relatively common reproductive disorder seen in dogs, and there have been suggestions that certain breeds may be more prone to developing this condition. One such breed that has been associated with cryptorchidism is the Border Collie.

Understanding Cryptorchidism

In normal development, the testicles of a male puppy descend from the abdomen into the scrotum shortly after birth. However, in cases of cryptorchidism, one or both testicles fail to descend properly, remaining in the abdomen or inguinal canal. This can lead to potential health issues, including an increased risk of testicular cancer, infertility, and hormonal imbalances.

Prevalence in Border Collies

While cryptorchidism can occur in any breed, there is evidence to suggest that Border Collies may have a higher prevalence of this condition compared to other breeds. According to a study published in the Journal of Small Animal Practice, Border Collies were found to have the highest incidence of unilateral cryptorchidism among 175 different dog breeds analyzed.

Possible Causes

The exact cause of cryptorchidism is not yet fully understood, but it is believed to have both genetic and environmental factors. In the case of Border Collies, it is speculated that there may be a genetic predisposition to this condition. Selective breeding practices could potentially contribute to a higher incidence of cryptorchidism in this particular breed.

Implications for Breeding

Cryptorchidism is considered a hereditary condition, and affected dogs should not be used for breeding. When breeding Border Collies, it is important for responsible breeders to carefully select mate pairs and screen for this condition to minimize its occurrence in future litters. By avoiding breeding dogs with a history of cryptorchidism, breeders can help reduce the prevalence of this condition within the breed.


Cryptorchidism is more common in Border Collies compared to other dog breeds. While the exact cause is not fully understood, it is believed to have a genetic component. Responsible breeding practices, including screening for this condition and avoiding breeding affected dogs, can help manage and reduce the occurrence of cryptorchidism in Border Collies. If you suspect your Border Collie may have cryptorchidism, it is important to consult with a veterinarian for proper diagnosis and guidance.
