My little dog was diagnosed with Lateral Patellar Luxation. I was referred to a surgeon by my regular vet and could not believe the cost. It was between $2500-$3500 for one leg and both knees were diagnosed. We have had one knee done so far and Purina Care covered 80% just like they said they would. They have been so kind and helpful through this whole process. They are the BEST and every time I go to the vet I tell every one in the waiting room how great they are. Would never be with out our PurinaCare insurance!!
