My dog Molly is a blue heeler. The blue heeler is a dog that is not afraid to protect its owner. Blue heeler, or also known as, Australian cattle dog, has a scissor-like bite. The blue heeler has a stocky body, and the tail is long with a slight curve. Black markings on a blue heeler are more than likely not fit for a dog show, depending on the people running it. Heeler puppies, when born, will be solid white due to crossing the dalmatian with other breeds to make the blue heeler.
The blue heeler is very active, and can sometimes be very aggressive if another dog or suspicious person is around. They need extreme exercise, or behavior problems will start. Blue heeler puppies should be socialized as soon as possible or they will start being aggressive with everybody. If not trained, they might start trying to herd the kids.
