The Benefits

The benefits of spaying or neutering include:

  • Reduced risk of developing cancer.
  • Less likelihood of running off in search of a mate.
  • Lowered levels of aggression, leading to better odds of finding and keeping a home.
  • Reduced numbers of unwanted pets.
  • Reduced spraying/marking behaviors.
  • Prevention of going into heat, bleeding, and yowling.
  • Improved health and increased life span.

Our primary clinic at 3300 Falls Road is open to the general public. However, your pet must meet these requirements to be eligible for our spay/neuter service:

  • Cats must be between 8 weeks and 7 years old.
  • Dogs must be between 12 weeks and 7 years old.
  • Dogs must weigh between 5 and 85 pounds.

Some dog breeds are ineligible. Pets must also be over 12 weeks old to receive a rabies vaccination. If your pet doesn’t meet these requirements, they may be eligible for spay/neuter surgery at our Wellness Clinic at 4007 Falls Road.

Low-Income/Free Program

Baltimore City residents with annual earnings below $25,000 (as an individual) or $42,000 (as a household) may qualify free or reduced-priced services. This program is funded by the Maryland Department of Agriculture, which aims to reduce the number of unwanted and abandoned pets in our area. To be eligible, you must live in a designated ZIP code (21215, 21216, 21217, 21218, 21223, 21225, or 21229) and participate in at least one of these programs:

  • EBT Card/independence card holder.
  • Social Security/VA Disability.
  • WIC.
  • Medicaid.
  • AFDC.


The cost to spay or neuter your pet runs from $40 to $100 per animal and includes surgery, rabies* and distemper vaccinations, and nail trimming. If your pet is cryptorchid (testicles have not descended), there’s an additional fee of $20 per retained testicle.

(*Only pets over 12 weeks of age are eligible for a rabies vaccination.)
