The Spay and Neuter Controversy

Spay/Neuter Controversy



There is currently a great controversy in the Animal Care Field regarding the “right” age to spay or neuter a pet and the “right” technique to use.

As there is no right answer right now, here are links to important research that can help you decide what is right for your pet:

The Ovary-Sparing Spay

The heat cycles remain and there is no protective effect for preventing breast cancer, but as you can read below, there may be longevity benefits to leaving the ovaries and removing the entire uterus including the cervix. This requires a longer incision, but may be a better option.
