It's been three weeks since I had to make one of the most difficult decisions I can ever remember and even now am rethinking my decision over and over. It all started the last Sunday of May. Boo which was my 8 and a half year old Shepherd threw up his dinner which was not common but, seeing part of a piece of paper towel knew he must have gotten some trash that he shouldn't have. As Monday came and went he did not want to eat, Tuesday same thing. I went and got him a can of food ( which was a treat to him) he ate the half can I gave him and I felt some relief. Wednesday evening after getting him to eat the other half of the can I noticed when I took him out that his urine seemed darker than usual almost brownish. So I'm thinking urinary track infection maybe worse case bladder infection. Thursday morning I called the vet and fortunately they had a cancellation so I took him in thinking they would put him on an antibiotic and all would be. O.k. The vet felt what she said was a large mass in the abdomen area and requested X-rays blood work etc. the X-ray came back and showed a mass but the vet could not tell what exactly it was attached to. We scheduled exploratory surgery for Friday morning...and she gave me the news I was not expecting or ready for. He had not only developed cancer but it had spread to most of his organs?. She recommended that I let him go while he was under sedation saying that there was little time left and that he would be in terrible pain. I just couldn't and still can't believe how a playful fun loving dog can go from one extreme to the other in a week. This is the first time I have been able to even type out this without totally blubbering like an infant. I think about him constantly wishing I could have had a better goodbye. I have seen and read other similar experiences so I know others are or have felt this pain. I just can't stop thinking of him and how much a part of our family he was.
