We've had two beagles and and two mutts. I guess my favorite dog was my mutt. She was our first dog, had the best temperment and was very healthy. She set a high standard for the pets to follow. Our first beagle was a character with a stubborn streak and multiple health problems. I loved them both dearly and now rate dogs on the Pokey/Lucy scale. Our current dogs fall somewhere in the middle temperment-wise and at the top of the scale health-wise. I really think I could love any dog.
