I can certainly relate to the love of a pet, both my love for the pet and his love for me. Totally faithful.
I have a Maltese breed of dog. I do a daily walk around my neighborhood and it is 1.7 miles complete trip. He loves this walk and if I drag my feet about getting on with the walk, he will harass me until I get up and go. Last Tuesday it was 6 degrees F and he was ready to go. He keeps me healthy.
