 Low Cost Clinics

Spay and Neuter

These clinics may be ‘full service’ or may specialize in high volume spay and neuter. Even with specialized clinics they will often offer additional services such as vaccination, microchipping, nail trims etc. and some offer testing (heartworm, FIV/felv) and even dental cleanings.

Please note that there can be additional charges related to spay/neuter surgery for things such as “in heat” fees, pregnancy terminations, additional pain medication, protective e-collars, undescended testicles etc. Check the individual clinics’ websites or call for their hours of operation and a complete list of services and costs.

Also, individual clinics may have varying age and weight requirements. At the time of scheduling they will give you specific details such as when to withhold food prior to surgery, that cats MUST be transported in carriers, and other pertinent information.

Base rates roughly range from $29-40 per male cat, $60-$75 per female cat and $65-$140 depending on either/or the weight and gender of the dog.

Choose which clinic best accommodates your needs. Most participating clinics cover the full cost of surgery including in heat fees, pregnancy terminations and cryptorchidism (undescended testicles), but be sure to ask individual clinics about possible additional charges which can vary by clinic. On occasion, some dogs require protective e-collars ($10-12) if they’re licking their surgical site and two clinics require vaccines at an additional cost ($5-23).

Some clinics may have an extensive wait list. While the Humane Society of Southern Arizona requires mandatory vaccines at an additional cost ($23), they sometimes accommodate more animals than the limit and can get animals in more quickly especially if they are in heat or pregnant. Guadalupe does not maintain a waiting list, but rather takes appointments on a first come, first serve basis at the beginning of each month until they run out of vouchers (usually in under 10 business days).
