I agree that your future companion will come into your life when it is time. It's the way all my dogs arrived in my life. I never went looking for any of them. Especially the BAZASCW... even Charlie was a "Hello I'm here."
I have lit a candle for Arwen that she learns to be on her own for a while. Dogs are pack animals so until she has a dog companion you are her pack. Wishing you both contentment and peace.
Love All Life, Thank You For Posting! :)
