Our medical bills are very extensive, even with wonderful vets who provide reduced costs. All of our rescue dogs are spayed/neutered, microchipped, and provided all shots. We also take in sick and injured dogs, including broken legs and spinal issues from abuse cases. Luxating patella surgery is very expensive, and we provide that, too. We also have standard administrative costs, such as signs, brochures, etc. since we have weekly pet meet-and-greet events at Petco and PetSmart. We also attend other Rally to the Rescue-type of events. All of us are volunteers, and we feed and shelter our foster dogs like they were our own. Hope this helps!
