Ovariohysterectomy is the medical term for spaying an animal. This procedure consists of surgical removal of the ovaries and uterus. If the ovaries are not removed, the bothersome heat periods still occur even though pregnancy is impossible. Surgery is usually performed after 4 months of age, preferably when your pet is not in her heat cycle.

Though it is routinely performed, spaying is a major abdominal surgery, requiring a general anesthesia and sterile operating techniques.

Prevention of pregnancy and heat periods is the main reason for the surgery, but the procedure is often necessary in treating severe uterine infections (pyometra), ovarian and/or uterine tumors, and some skin disorders.

Advantages for spaying your pet before their first heat cycle:

  • There will be no heat periods.
  • There will be no unwanted puppies or kittens.
  • No uterine infections.
  • 50% reduction in breast cancer incidence.


  • Won’t spaying my pet make her fat and lazy?

    Won’t spaying my pet make her fat and lazy? No. Obesity is due to excessive calorie intake. Proper feeding and exercise can control weight.

  • Will it change their personality, disposition, or intelligence?

    No. Your pet’s personality does not fully develop until about 1-2 years of age. If there is a personality change in a pet spayed at a young age, it would have occurred without surgery.

  • Shouldn’t they have a litter first?

    No. There is no advantage in allowing your pet to have a litter of puppies/kittens.
