re: What's the most versatile breed of dog?

I've had labs, german shepherds, and curs and all were fantastic dogs.

That being said, I have a Blue Heeler now and will prob have one from here on out. She's sweet, but protective, especially of my newborn. Super smart and is with me step for step. She will blood trail and will work the hell out of cows. She loves to play fetch. She listens better than any dog I've had and she doesn't go far from the house. She is very energetic, so throwing the ball for 30 minutes or so a day is a requirement.
