Testosterone for dogs

Updated November 21, 2016

Neutered dogs do not produce testosterone. Neutering is typically performed to prevent unwanted breeding, as well as for some behaviour and medical issues. However, there are certain health issues that may dictate that neutered dogs receive testosterone supplementation.

Neutering is a simple surgical procedure to remove the testicles of male dogs. Neutering effectively stops the production of testosterone and makes breeding impossible.

Neutering and Health Benefits

Neutered dogs have many health benefits, including a reduction in testicular tumours, fewer prostate related diseases, a reduction of perianal tumours, and a smaller number of hernias. These health benefits are all a result of the removal of testosterone from the system.

Testosterone and Behavior

Testosterone affects the behaviour of dogs. Eliminating testosterone through castration typically results in a reduction of aggression, roaming, and indoor marking.

Testosterone and Urinary Incontinence

While there are a multitude of reasons to eliminate testosterone from your male dog, there are some instances where testosterone is advised as a treatment for certain health conditions. Urinary incontinence sometimes stems from the loss of testosterone in the system in neutered dogs. Males suffering from hormone-related urinary incontinence usually improve with a testosterone hormone replacement.

Testosterone for Alopecia

Some forms of alopecia (hair loss) are caused by a lack of testosterone and can be effectively treated with a testosterone hormone replacement.
