Compassionate and skilled veterinarians and technicians utilize state-of-the-art equipment to safely surgically sterilize thousands of dogs and cats each year using the highest standards of care.
“I took my very nervous dog to get neutered. Joybound’s team was super friendly and understanding of the fact that sometimes it takes a little patience with some dogs.”
– Jose, Joybound Spay/Neuter Client

On-Site Spay/Neuter Clinic
Our clinic has seen an increase in demand for our limited appointments. We are currently booked up to 12 weeks in advance. For additional options for spaying/neutering your pet, please view our collection of spay and neuter resources for your pet’s needs.




Our Lynn & Dolores McCoskey Spay and Neuter Clinic is located at our Walnut Creek headquarters and is open (by appointment) to pet guardians. In addition to their sterilization surgery, animals can be administered with free nail trimming, ear canal checks, post-surgery pain medication, and e-collars. Pet microchipping and vaccinations are available for a small fee.
Please note: Our maximum weight limit for animals receiving services is 100 pounds. Brachycephalic breeds (such as English Bulldogs, French Bulldogs, Pugs, and Persian cats) have a higher anesthetic risk and need additional monitoring, requiring an additional fee. A very limited number of surgery appointments are available for brachycephalic animals.

Pet Guidelines for Spay/Neuter
- Pets must be healthy and not displaying any signs of disease. If your animal has a chronic medical condition, notify our clinic in advance. Our veterinarians will need to review medical records to determine if our clinic can serve your pet.
- Pets must be in the following age ranges:
- Female dogs must be between 12 weeks and 4 years of age.
- Male dogs must be between 12 weeks and 7 years of age.
- Cats (male and female) must be between 8 weeks and 7 years of age.
- At our on-site clinic, all pets must weigh at least 2 pounds and no more than 100 pounds. For mobile clinics, pet must weigh no more than 50 pounds due to space limitations on the vehicle.
- The guardian must bring proof of current distemper combo and rabies vaccination within one year. The vaccine requirement applies to all animals, including those that are indoor only and who may not have had the full set of vaccines.
- Some brachycephalic (flat faced) breeds of dogs and cats may be altered at our veterinary facilities in Walnut Creek. No brachycephalic breeds are accepted on-board the mobile clinics. English and French Bulldogs are not eligible for any of our spay and neuter services, as these breeds have a significantly higher risk when undergoing anesthetic procedures. Please see a full-service veterinary hospital to pursue specialized anesthesia.
Our veterinarian may disqualify any animal if they determine the animal is not medically sound for surgery.
Guidelines for Pre-op & Post-op Care
- Please withhold food after midnight the night prior to surgery. This is an important safety precaution, as animals can inhale vomit while under anesthesia.
- Dogs must be on leash; cats must be in a carrier (no traps). If you have an appointment for multiple cats, they each need their own carrier.
- Guardians must bring proof of current rabies and distemper vaccinations. No vaccinations or preoperative blood testing will be provided.
- Follow-up care will not be provided by Joybound. Guardians will be sent home with detailed post-op care instructions.
