Welcome!
The Longmont Humane Society Well Pet Clinic is proud to provide quality, affordable veterinary service to dogs and cats in our community at our facility in Longmont, CO. As a matter of policy, the Well Pet Clinic only offers on-going services to animals from households where all pets older than 6 months are spayed or neutered (or have a medical exemption from a veterinarian). We are currently booking about 2-3 weeks in advance for routine appointments or spay/neuter surgeries, and 5-6 weeks in advance for dental surgeries. In an effort to provide high quality service to our existing clients and Longmont Humane Society adoptees, we are unable to accept new clients at this time – except for spay/neuter surgeries which are available for all.
The Well Pet Clinic is open for veterinary services by appointment only. Please email vetservices@longmonthumane.org or call (303) 651-0610 to schedule an appointment.
- All services offered by appointment only.
- Please note that payment is due at the time of service.
- We offer discounted rates to low-income community members who qualify for PAC – please see information and application at the bottom of this page.
If you need a medication refill for your pet, please call 303-651-0610 or email vetservices@longmonthumane.org to request the refill. You will be given pickup and payment instructions when the refill is ready.
