Our 3 year old Great Dane, Moses, was diagnosed with grade 3 Mast Cell Carcinoma 6 mos. ago. After the initial surgery & biopsy confirmed the diagnosis we have gone the chemotherapy route with him. He's in remission right now and VPI has covered exactly what they state in the policy, and in a very timely fashion. Because of Mo's sickness, and our love of the breed, we've purchased another Dane puppy and have him already signed up with VPI.
