Early Neuters vs. Testicular Cancer
While most people have heard of the beneficial behavioral effects of neutering male dogs and cats, they may not be aware of some physical health benefits. Neutering will totally prevent testicular cancer. Testicular tumors account for 90% of all cancers originating from the male reproductive system. Most tumors are contained to the testicles, but may spread in 10-20% of the cases.
Although intact canine males with a median age of ten years are highly predisposed, breeds at an increased risk include Boxers, German Shepherds, Afghan Hounds, Weimaraners, and Shetland Sheepdogs. The pictures aren't pretty to look at but they are important to see what can happen. Thanks to Dr. Daniel A. Degner, Board-certified Veterinary Surgeon (DACVS) for sharing these photos.
Neutering will also significantly reduce prostatic hyperplasia, an enlargement of a male sex gland located near the bladder. An enlarged prostate can be painful when interfering with urination or causing bowel irritation and straining when it swells, much like it does in people.
Neutering by four months will take care of all these concerns!
