Wellness Appointments:
Wellness appointments at SNAP are for preventative care only, which includes such services as vaccination, microchipping, heartworm testing (dogs), FIV and Feline Leukemia testing (cats). SNAP does not see sick or injured pets, and your pet must be feeling well in order to receive vaccinations. If your pet becomes unwell prior to his/her visit, please contact us to reschedule your appointment.

All patients being seen for wellness require an exam.  An exam is also required annually in order to be dispensed prescription flea/tick medication.  All dogs are required to get a heartworm test annually in order to be dispensed heartworm prevention. A list of our current services and prices can be found on our price list by clicking here. All prevention is currently dispensed via our online pharmacy by clicking here.

It is SNAP’s policy that pets who are over 6 months of age and not spayed or neutered may be seen ONCE in our wellness clinic, after which time they may not be seen again until they are spayed or neutered. For information about spaying and neutering, including how it improves the health of pets and the community, please click here.

SNAP recommends that all patients have a primary full-service veterinarian that can treat any injuries or illnesses that arise, as well as perform routine blood work and dental exams. At SNAP we want to help you keep your pet healthy by making preventative care affordable, but all pets will need care at a full service veterinarian during their life time and we recommend you find one you like in advance before an urgent situation arises.
