I have 2 dogs. Both insured with Trupanion. One is my problem child, the other extremely healthy. Trupanion has helped me with the medical expenses for my female who has had bilateral knee surgery and resulting arthritis. She's only 3 1/2 years old, has allergies and anal gland problems in addition to the ongoing knee problems. Thank goodness for Trupanion! They are a wonderful company (and I have other pet insurance with my previous generations of dog and cats) and have continued to help with her medical care.
