Coffee House Girl,
So sorry for your loss. A dog can be a girl's best friend as well.
I have a black lab I got from a rescue organization and another dog and 4 cats that I "rescued" from my kids. Rescue animals seem to have more of a sense of loyalty than non-rescue.
I like the following quote.
"He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion."
