More: Rocky is currently 13.5 years old. He is battling grade 2 Pulmonary Adenocarcinoma (lung cancer). He was underwent a gnarly surgery to remove one of his lung lobes and was only given eight months to live, which is a date he just passed. Since being diagnosed with lung cancer, Rocky has summitted our highest mountain yet, taken road trips, hiked hundreds of miles, and overall, walked into this battle head on, while fighting with tremendous bravery and strength. I want everyone to know that little dogs are capable of so, so much and Rocky is proving that every single day!
