Carrie I am so,so sorry.
I am sitting here just numb because we have just had the same happen to us tonight. Our rotweiler Sally was with us just 4 years (we took her in as a stray) and she was about 10 or 11 now I guess, we never knew. She started throwing up and not eating yesterday, I took her to the emergency ER and she was given an injection for the nausea. Today she got worse, we took her back in and she died shortly after we arrived. We are so sad.
Anyway I'm sorry to hijack your post but I feel your pain so much tonight. Losing a pet is so very hard.
Take care,
Linda
