We have a red and a blue heeler. They are wonderful dogs. Have never trained them to work cattle. They just seem to come into on their own. VERY intelligent dogs. Son uses the blue for 4H also. She is very easy to teach and loves to work in the show ring about as much as she loves working cattle. Other son is thinking about using the red for 4H this year. The red isn't a year old yet and hasn't had any training yet so will have to see how that goes. One mistake we made with the last red was tone of voice. When he was riled up about a stranger being on the place, we used a soothing tone to try to settle him down. Turns out with heelers, you need to use a firm tone to let them know you are in charge of the situation. Guess I was just to use to the lap dogs I had as a kid. Once I figured out Heelers will take control of a situation if I don't, everything was fine. The next problem I need a solution to is - how to keep them from killing my ducks and cats. Any ideas out there?
