When Is The Best Time To Neuter A Male Dog

?

Dr. Ian Dunbar Responds: Neutering a male dog is not an easy decision to make, and I understand why some people choose not to neuter their dogs until they are older, but in many cases it is necessary for the health of your pet. When veterinarians like myself perform surgery on pets such as cats and dogs (or other animals), we do so out of concern that these animals may be suffering from diseases that can be prevented by neutering. For example, testicular cancer has been found mainly in intact males; my own female cat sadly died last year from this horrible disease. It is also very common for long-term medical problems to develop in intact males due to abnormal development of reproductive organs or sperm production problems related to age when neutered early enough before prostate enlargement occurs with maturity—a condition called BPH (benign prostatic hyperplasia). Allowing a male dog or cat to mature without being castrated will often result in serious medical complications developing later in life such as arthritis and bladder stones. In addition, spaying prevents heat cycles which cause aggression between unneutered females during breeding season when estrogen levels rise dramatically resulting in overpopulation and unwanted litters produced by indiscriminate breeding. And lastly, surgical removal of the testes results in loss of testosterone production and hence libido and aggressiveness if left unchecked which can lead eventually into uncontrollable behavior including aggressive territorial marking urine spraying pottying urinating inappropriately sexualized
