I'm sitting here crying my eyes out and just feel so bad. In May we had surgery on our 13 year olds spine because it was getting very hard for hm to walk and we thought it might help. Its been 3 months and he can't walk at all on his back legs. I bought a harness to help take him out he's 100lb dog. But its getting harder and harder to do. I'm getting to the point were I get upset with him and I don't want to do that its not his fault. And I can't bring myself to put him down. The only problem he has is his legs. The rest of him is sharp I think thats why I can't bring myself to do it. I'm so upset I feel like I'm letting him down. And I just can't stop crying today.
