We had to put my dog to sleep. I had her 11 years, I was devestated. But she was in horrible pain and I didn't want her to suffer any longer. The vet wasn't sure what exactly it was, but from what he saw on the xray, it was a death sentence, she hated all the tests and poking and prodding so I didn't see any reason to put her through any more just for the end result to be euthanised. The vet is pretty sure it was cancer. She was to large to burry in the yard, but I saved her tags and keep them on my key chain. I still have all her stuffys. Can't bring myself to getting rid of them.They make me smile when I look at them. She was hyper, useless, illmannered, stubborn, disobedient mutt. I wouldn't have traded her for anything. She had a good heart, and I like to think about her. At first I couldn't without crying, now, I smile when I think of how much she drove me crazy. You do whats best for your beloved pet, he dosn't understand why he hurts.But he's had a very good life, and he knows he's loved. And thats what matters the most.
