My heart breaks for both of you in reading your post about Fluffy, I too have had to make that decision that we all never want to ever have to make, but in the end my husband and I knew it was the right thing to do, sure we questioned everything, ourselves, the dr, even Ginger when she herself was showing us that it was time for her. We never wanted to let her go, she was all I had left from my cockers that I had had for 14yrs, but trust me, she will forever thank you and tim for putting her at rest and letting her have peace. In more ways than you know she is showing you that it is time, you have to accept it and do what needs to be done. I know this is the most horrific heart breaking decision, but be strong for her. my prayers and my thoughts will be with all of you, God bless you and give you peace of mind.
hugs to you.
