Im an Ex soldier. I have been deployed to war. I have seen death and I have killed. That seems so long ago but coming home has reminded me where i am strong and where i am weak. I can see a dead body, or a dead anything and not care too much. But i came home to find my dog in her old age. She is losing her ability to walk. She is always tired. Has caluses on one of her legs. Losing weight. I can take seeing death but watching something die before my eyes is quite a bit harder to deal with. I just want to know what the right course of action should be with my dog. How close is she till the end? She a female boxer.
