Awesome to hear. We had a lab that had lung and anal cancer. Vet gave her ~6 months. She lived almost two years after that. Felt like losing a family member.
I lost my childhood Beagle to anal cancer years ago. He was too old to do a surgery on. My sister had a Jack Russell that had cancer. They did surgery and with the type of cancer she had the prognosis wasn't good. I guess they got it all because she lived several years more and it never showed up in testing again.
