I had to put my Springer Spaniel down yesterday. It was easliy one of the hardest things I have ever had to do. I took him to the vet two weeks ago thinking he had some type of infection and found out he had acute leukemia and he was given one month to three months left. Dogs truly do hide the pain they are in. He was extremely loyal till the end. I was truly blessed to have such a good dog an companion. RIP Otis.
