Because we see a large volume of clients, we are able to charge comparatively less than would be charged at other veterinary practices for similar services. When clients miss appointments or reschedule with less than 24 hour notice, we see fewer patients, making it difficult to maintain our affordable prices.

To maintain our prices we have established a Missed Appointment Policy/Deposit Requirement where clients are charged $30 non-refundable surgery deposit. The deposit will be applied to the cost of the surgery. This policy allows us to continue to offer the community affordable veterinary care.

Vaccinating your pet supports the health of our community’s dogs and cats. Our experienced veterinary team will help you determine which vaccines your pet needs. If your pet has needs that we cannot accommodate, we will refer you to a low-cost partner. Vaccinations are only available on the clinic days listed below.
