Spay and neuter procedures can significantly reduce the risk of certain cancers and other health conditions in pets. Female pets have a lower chance of developing uterine and breast cancers, while male pets benefit from a reduced risk of testicular and prostate cancers. These procedures also support better long-term health and help improve your pet’s quality of life.

Spaying and neutering can also lead to positive behavioral changes in pets. The procedure may reduce roaming, spraying, and mounting behaviors in males while eliminating heat cycles in females. Pets may also show decreased aggression and a lower desire to escape in search of a mate. These benefits help create a safer and more comfortable environment for both pets and their families.
Most pets are typically spayed or neutered around 5–6 months of age, although the ideal timing may vary. In many cases, females benefit from being spayed before their first heat cycle to further reduce health risks. At Spencer Animal Hospital, we evaluate each pet individually to determine the best time for surgery based on their size, health, and overall condition.
