I just wanted to let you know, how much I understand what your going through. My Canillia has cancer right now. We have to carry her out side for her "nature calls" she only has the use of 3 legs right now and it looks like the other ones going bad now too. So we too are trying to decide when to let her go.

We look at her sometimes and she seems so happy even though she going through this. Other times we wonder if she really is happy. To decide what to do is so hard, we don't want to be with out her, she a great dog. But we asked our selfs everyday, if it was us would we want to live like this. The answer to that will tell us when it's time, if she doesn't first.

Your heart knows.

Good luck to you and be strong.
