We adopted an ~8 year old rescue dog last summer and signed up for Trupanion coverage as soon as he came to live with us. Six months later, he was diagnosed with cancer. Trupanion reviewed his records and processed the claim quickly. Reimbursement checks arrived about 10 days after they were approved. Additional treatment claims are being approved as they occur, though beware that no exam fees are covered, even for follow-up visits.
