Vet Services. Shelters do more than just house and adopt out animals. They provide veterinary services to the community. This can include vaccinations, spay and neuter clinics, and flea and tick dipping. Any animal is welcome at a shelter for these services. Shelters perform vet services on purebred dogs bought from breeders, stray cats taken in by a family, and even farm animals like horses and goats. The cost of these services is lower than at other clinics. Trained personnel at the shelter can administer shots and do procedures. Some shelters provide a visiting veterinarian on staff. These services can vary by location, so call ahead and determine which ones are available in the area.
