What are the physical results of these surgical procedures? n In the female dog or cat, the ovaries and uterus are removed. This will end the heat cycles, thus there will be no more pregnancies. n In the male dog or cat, the testicles are surgically removed. This will result in the lack of sperm production and the cessation of testosterone production.

At what age should my pet be spayed or neutered? n The average for sterilizing your pet is 5 – 9 months. n Many veterinarians are sterilizing pets as young as 8 weeks with no ill effects. n Puppies and kittens recover quicker from surgery than adults. n Sterilizing puppies and kittens before 4 months of age will assure that they will not have a first heat cycle.

Misconceptions about spaying and neutering. n My pet should come in heat before she can be spayed. It is actually better for her to be spayed before her first cycle because this will reduce the incidence for mammary tumors.

Misconceptions n My pet will get fat and lazy. With the removal of testosterone and estrogen, some animals will have a slower metabolism. The owner needs to reduce the amount of food accordingly. When sterilized at a young age, most animals will continue to stay active.

Misconceptions n My dog will not guard my home after having the surgery. n Dogs will continue to protect their property. The only behaviors that will change are those controlled by the sex hormones. n It is recommended to neuter or spay an aggressive animal, in an attempt to reduce the aggressive behavior. Sterilization may not stop the aggressive behavior because aggressive tendencies may be caused by environment or lack of training rather than sexual reasons

I want my children to see puppies or kittens born. n There is a pet population explosion today.
