Dog Spaying and Neutering

There are a few very important reasons to have your pet spayed or neutered. Spaying helps to prevent breast cancer, infection of the uterus and stops your pet from going into heat. Neutering prevents many aggressive behaviour problems in your male dog and also prevents testicular cancer, prostate disease and hernias.

What does neutering/spaying do to a dog?

Spaying is the complete removal of the ovaries and uterus, and neutering is the complete removal of the testicles. Spaying and neutering your pet can also cause weight gain. Our staff can discuss methods of nutrition control and exercise to help prevent unwanted weight gain.

Why is it important to neuter/spay my dog?

Spaying/neutering your dog can help unwanted behaviours such as aggression and marking territory. Altering your pet can also be beneficial to help prevent diseases such as mammary/testicular cancer and uterine infections. Spaying/neutering can also help with the overpopulation of dogs.

How old should a dog be before they are neutered/spayed?

Our doctors recommend spaying/neutering your dog between 4-6 months of age. If you are concerned about breed-specific ages, our staff is always eager to discuss any concerns you may have.

How much does it cost to neuter/spay a dog?

The cost of a spay/neuter can vary depending on the weight of your dog and options that you may want during the procedure such as Intravenous Fluids to help with blood pressure and flushing the vital organs of any medications used during the spay/neuter. Pre-Operative bloodwork can also provide a clear picture of organ function prior to surgery. For more information, kindly give us a call at one of our three locations, and one of our team members will be happy to assist you!
