You did the right thing in helping poor Ty cross over, it sounds as if he was in a terrible state.
Its been said so often that our boxers will let us know when its their time to leave us..You did for Ty the most unselfish and loving final act we sometimes are forced to make, despite all our efforts and reluctance we have to do what is best for our babies..I know the void in your heart right now is overwhelming...
My heart breaks for you,sending you hugs and healing vibes...
