Seven Reasons to Spay or Neuter Your Pet

February 23, 2011

Yesterday, February 22, was National Spay Day and some consider the entire month National Spay and Neuter month.

Spay is the colloquial term for ovariohysterectomy. Neuter, sometimes called altering, is the surgical removal of male reproductive organs or testicles. Both procedures have the same result: they prevent unwanted pregnancies.

But wait — these procedures have health benefits beyond preventing unexpected litters of puppies and kittens. The Animal Medical Center staff gives these seven reasons to “fix” your pet even if it isn’t broken!

1. Prevent pyometra a common, life-threatening uterus infection of unspayed dogs.

2. Eliminate the risk of testicular cancer and uterine and ovarian cancer.

3. Decrease the risk of prostatitis, a bacterial infection of the prostate.

4. Decrease aggressive behavior, especially in male dogs, helping to prevent dog bite injuries in humans.

5. Decrease the risk of breast cancer in both dogs and cats, especially if she is spayed before 6 months of age.

6. Avoid stinky male cat urine on your walls, drapes or bed.

7. Save approximately 4 million lives annually. These lives belong to unwanted dogs and cats euthanized in America’s animal shelters.

Thanks for posting this! I feel like I am seeing a trend in pet owners to wait on having their pets spayed/neutered until their older. I wish this wasn't the case. I think spaying larger/adult dogs carries a greater risk of complications than it does with younger dogs/puppies. As a side note, I performed a life-saving pyometra surgery on a 12-year old cat earlier this week! Here's a link to the article I wrote about it:
