Pet Neutering

While both are routine sterilization surgeries, “neutering” (or castration) refers specifically to the surgical removal of the testicles in male pets. “Spaying” refers to the surgical removal of the ovaries and uterus in female pets. Both procedures permanently prevent reproduction and provide significant health and behavioral benefits.

For male cats, neutering is generally recommended around 5 to 6 months of age, ideally before they develop the habit of spraying urine to mark territory. For male dogs, the timing depends on their adult size. Small to medium dog breeds are usually neutered between 6 to 9 months of age. Large or giant breeds may benefit from waiting until they are 12 to 18 months old to allow their bones, joints, and growth plates to fully mature.

You should examine the surgical site daily. Please contact Erin Mills Pet Hospital if you observe any green or yellow oozing discharge, open gaps in the skin, significant bruising that spreads, a foul smell, or an incision that feels excessively hot or swollen to the touch.

Yes, significantly. Neutering removes the primary source of testosterone, which drives instinctual male behaviors. It reduces or eliminates the urge to roam away from home in search of a mate, curbs aggressive territory-marking behaviors (like spraying urine indoors), and drastically decreases frustrating mounting behavior and testosterone-fueled fighting with other animals.

Neutering provides excellent long-term health benefits for your pet. It completely eliminates the risk of testicular cancer, which is common in older unneutered dogs. It also significantly lowers the risk of non-cancerous prostate enlargement (benign prostatic hyperplasia) and painful prostate infections, helping your pet live a longer, more comfortable life.
