I have 2 Pit Sulls (StaffordShires). Rory a purbreed tore the tendons that are attached across the front of the knees. She tore one knee one year the next year she tore the other. The cost for each around 2,000. Without this insurance, we would be out of 4,000 over the two year period. I am glad I have VPI pet insurance. They soften the blows.
