More: Curtis will forever be a goofy 1.5 year old Pyrenees mix. He died in August of 2021 from a rare and aggressive form of sarcoma cancer. This photo was taken shortly after he was diagnosed. After his diagnosis, we made the most of every day with adventures in the woods and all day play. Curtis loved to swim and visit the trails and creek. This photo was taken at his favorite spot at the end of a very fun day. Curtis had short but full life.
