More: Wall-E has been battling lung cancer for just over a year. He had one lobe of his lung removed last fall and endured chemotherapy until January. Everything was going well for several months, but another tumor appeared in a different area of his lung. A new chemotherapy drug worked for a while, but the tumor began growing again in spite of the treatment. He is now off the chemo and is enjoying the days he has left with his family and friends. This picture was taken on his 13th birthday. He loves long walks, treats, and watching tv with his human brothers.
