We have been talking about getting another dog so that we can have a guard dog to protect Bobby’s shop from any more burglars. I wanted an adult dog and he wanted a puppy. We compromised and got one that is about 5-6 months old. He is a Red heeler mix, and still has that straggled-out puppy look; but his body should fill in to be a nice blocky heeler look by the time her is a year old. Heelers are one of the best watch dogs you can have, even though they are not as large as a Rottweiler or pit bull, but between him and Tootsie (who is part Blue Heeler), they should do an excellent on of protecting us.
