I'm so sorry. I've been on vacation so I haven't been here a lot. A lot of us know first hand how hard that decision can be to make. And it's normal to have guilt. I had a hard time getting rid of mine and sometimes I still feel a twinge of it. But, I don't doubt what I had to do and you shouldn't either. It's our last gift of love we can give them after all the years of love and happiness they've given us. Duke and all the other PT dogs will make sure Thunder has an easy time arriving at the RB. And all of Catmandu's cats will throw him a huge party. It's not goodbye. Just till we all meet again.
