I purchased this insurance when our Miniature Schnauzer was a puppy. Then she was diagnosed as having a portosystemic shunt when she was about two years old. Ever since then, she has had to stay on a special dog food and take a medication daily (for about three years now). This insurance company has been wonderful, reimbursing me with 90% of the cost of the medication and ongoing blood work and urine tests. I am so glad I purchased this insurance!!!
