Reasons to Spay and Neuter in Casper

Our most common surgical procedure, spaying or neutering is a routine way to remove your pet's reproductive organs and improve their chances at a long and healthy life. But why is this important, and does your dog or cat really need this procedure?

Intact cats and dogs have higher risks of certain health and behavioral problems. For example, after male cats reach sexual maturity, common behaviors include "spraying" urine to mark their territory and roaming (or trying to escape) in order to breed. Unaltered dogs and cats also face higher risks of prostate or ovarian cancer, urinary infections, and other long-term or recurring health problems.

Overpopulation is also still a huge problem in Wyoming and the rest of the United States. Millions of dogs, cats, and other pets lose their lives every year because shelters don't have enough room for every unwanted litter or stray pet. Spay and neuter your pets as soon as they're eligible for surgery, and they won't be the only animals to benefit.

What Happens During Spay and Neuter Surgeries

Your pets are part of the family, so you deserve to be fully informed about their medical procedure. At our Casper animal hospital, we welcome questions about the spay or neuter process, but it helps to know the basics before you come in.

Spaying involves the surgical removal of the uterus and ovaries, a simple procedure that requires one incision and takes up to an hour to perform. Neutering is a simpler surgery that involves the removal of both testicles. We also perform minimally invasive laparoscopic surgery.

Preparing for Your Casper Pet Surgery

Even though this surgery is very common, we take every precaution to minimize your pet's risks and keep them safe and comfortable. We perform thorough wellness exams prior to every spay and neuter surgery, as well as preanesthetic labs. Our goal is to determine whether your pet is healthy enough for anesthesia and surgery, calculate exactly how much anesthesia they will need, and learn more about their overall wellness. Your Casper veterinarian will perform a pre-surgery assessment before making the first incision.

Like every Casper pet surgery we perform, your pet's spay or neuter procedure will include full and careful monitoring of all vital signs and gradual doses of anesthesia to reduce the likelihood of complications. Fluid therapy is provided to maintain blood pressure and allow IV access. Pain medication is always given, and sent home too. We will also give you precise instructions for the night before surgery and recovery in the days that follow.

Is your dog or cat still intact? Our Casper veterinarians offer free consultations for new patients, and we encourage all our current patients and their families to take advantage of our spay and neuter services. Just call (307) 472-5600 to schedule an appointment for your Casper pet. We look forward to fighting pet overpopulation together.
