this breed of dog is known for being a one person, "Velcro dog." They always want to be where you are and are known for being "nosey" and curious They are known for being "hard headed," this is just a way of saying their people have to know at least 10 ways to skin a cat. Cattle Dogs have a profound sense of fairness and know when they're being mistreated. The more intelligent the Heeler, the more difficult to train. They have their own ideas of how things should be done, their human has to convince them to come around to their way of thinking so they can work as a team. Srsly, I don't know why this dog isn't already on the list. We train because we know whats goof for us, a Cattle Dog will wreck your home if they haven't been exercised and trained sufficiently.
