My 1 year old cairn terrier Patrick has had a hard first year. Several episodes of gastroenteritis and pancreatitis. Without VIP i don't know what we would have done........well we would be in the poor house!!!! We have found a preventative that seems to be working!!!!!! Thank God. He is a family member to us and I would never not have VPI for my dogs now and in the future. They are the best!!!!! I have told several other pet owners about the company and at least 2 have got a policy.
