Spay & Neuter

Spaying or neutering your pet can help them live a longer, healthier life, minimize behavior problems, and help control the population of unwanted dogs and cats.


According to the American Veterinary Medical Association, nearly 12,500 puppies are born in the United States each hour. Spaying females or castrating males eliminates unwanted litters, which contribute to thousands of euthanasia procedures and millions of stray animals. Additionally, these procedures can minimize behavior problems and help your pet live a longer, healthier life by reducing the likelihood of certain cancers and tumors.

When should I have my pet spayed or neutered?

In general, we recommend spaying or castrating small dogs and cats between 4-6 months of age. With large breed dogs, we often recommend delaying the surgery until they are 6-12 months of age.

Why should I have my pet spayed or neutered?

There are many benefits that come with spaying your female companion animal. They include helping to control the stray dog and cat population, eliminating the sometimes 'messy' heat cycles that attract male dogs, and preventing diseases in your pet such as pyometra (infection in the uterus) and mammary cancer. Additionally, research has shown that spayed pets live longer than pets that have not been spayed.

There are also many benefits that come with castrating your male companion animal. These benefits include helping to control the stray dog and cat population, eliminating undesirable and embarrassing behavior, and preventing diseases in your pet such as prostate disease and testicular cancer.

How is a spay or neutering surgery performed?

Spaying, also called an "ovariohysterectomy," is a surgical procedure in which both ovaries and uterus are completely removed from your female pet while they are under general anesthesia. Castrating refers to the surgical procedure in which both testicles are removed while your male pet is under general anesthesia.

Before the operation, we will assess your pet to minimize risk. While your pet is under anesthesia we take individual care for the safety of each pet. Our certified technicians and doctors are trained in advanced monitoring to ensure your pet's comfort.

Your pet’s safety and comfort are our primary concerns when performing a spay or castration. We routinely use a IV catheter and fluids on canine spays and castrations, as well as feline spays.  This is important for maintaining blood pressure and perfusion to the kidneys and other organs as well as allowing immediate IV access in the event of an emergency.  We use advanced pain management techniques in conjunction with anesthesia to make sure your pet is as comfortable as possible during the procedure and after they are discharged. Our spay and castration patients receive 2 or 3 different injectable pain medications during the procedure and usually go home with oral pain medication. We also perform local anesthetic blocks at the surgical site.  Proper pain management makes the procedure as comfortable as possible and allows for faster recovery.


We use Sevoflurane anesthesia to safely and effectively put your pets under for surgery. This type of anesthesia is one of the best available and is considered the gold standard for human care as well. It also helps pets recover after anesthetic procedures. We’ll monitor your pet the entire time they’re under anesthesia and make sure everything goes smoothly.

Recovering from Surgery

Making sure your pet recovers smoothly and safely from surgery is just as important as the surgery itself. After your pet comes out of surgery, we’ll give you detailed instructions on how to provide the best aftercare for your pet so that they’re back on all fours faster.

Our Mansfield veterinarians will give you tips for:

  • Activity levels – Your pet will need to limit their activity while they’re recovering from surgery. Activities like running and jumping are discouraged, but we’ll let you know what your pet can and can’t do while they’re recovering.

  • Food and water – We will let you know what and when your pets are allowed to eat and drink. Sometimes, you’ll have to wait to give your pet a full meal, and sometimes they’ll be allowed to have a small snack.

  • Medication – We will send you and your pet home with medication that will help them recover quickly and painlessly. We’ll give you full instructions so you know what to give your pet and when.

  • Wound care – You will need to monitor the area that was operated on to make sure it heals without infection. Depending on your pet’s procedure, we might send your pet home with a protective collar to keep your pet from scratching or licking their wound.
