I am so very sorry about Peg. I just had a "feeling". That is why I was hesitant to post...but I just had to...I could not forget your sweet boy. 12 is a great old age for a big dog, but then you know that, and it is never "time" as far as we are concerned. :(
Take care, my friend and give that Luna girl an extra hug from me...and one for yourself, too.
Love,
Jeanie
