Spay and Neuter Surgery in River North, Chicago

Helping your pet start their life on a healthy note is critical. The care they receive in the first year of their life includes exams, vaccinations and other preventative treatments to protect them from disease. Likewise, we recommend spay and neuter surgeries for cats and dogs at a certain age to prevent or reduce problems they might encounter later. At Companion Animal Hospital, we’re passionate about promoting pet health and reducing overpopulation numbers in River North and surrounding neighborhoods.

When Should My Pet Be Spayed/Neutered?

Generally, pets can be spayed and neutered between 6-7 months old. However, this depends on the pet’s health, size and breed. Larger dogs often need to wait until they’re between 9 months and a year old, since they spend more time growing and developing.

Since our pet’s health is our primary concern, we want to help you choose the time that works best for them. We also encourage you to ask questions to fully understand the procedure your pet needs and how it will benefit them in the future.

We understand that you might have concerns about spaying/neutering your pet. Our team is available 7 days a week, so don’t hesitate to call (312) 643-2901 if you need to consult with your veterinarian.
