I am so sorry for your loss. Phoebe was a beautiful girl. I know how difficult it is to make the decision to let them go. And your story brought on the tears. When I let my Taz go he let out a sigh after the injection, almost like he welcomed it. But your Phoebe's reaction is heartbreaking.
Please know you did what was right. I know it doesn't seem like it right now. It took me a long time to realize it. At times I still question my decision, but then I think about how sick he was and what kind of life he was living.

Hugs to you Rhonda and RIP Phoebe.
