Its been a week since I had to put my dog Snowball to sleep. It was the hardest thing I had to do. He was 13 years old and my best friend. He acted like nothing was wrong with him. He was so glad to see us all the time. To me it looked like he had hemorrhage only, until I called the vet and asked him about it, and he said dogs don't get that. Well RED FLAGS came up and I took him in right away. The doctor said he had "Perianal Circumanal Adenomas" (TUMORS) along with other serious problems. Has anyone ever heard of this disease.
