My dog, Sundance, nearly died as she went from her usual energetic and lively self to not eating, drinking or leaving her bed in the matter of about four days. It took several days of treatment and several tests to determine she has Addison's Disease, a chronic disease where the adrenal glands do not function properly and stress hormones become toxins in the body. As long as she stays on medication the rest of her life, she will be perfectly fine with a normal lifespan. Thankfully, PetPlan has been there every step of the way - complete and prompt payment for the initial diagnosis and treatment as well as each month's medicines. They have been very helpful and answered my questions patiently and thoroughly. I couldn't ask for a better insurance company.
