Second, begin consistent and several times a day recall training. This is sometimes referred to as the "come" command. This training process should start in the house where the problem is not associated with in any way. Make sure you have lots of very enticing treats on you before you start your training session.[/B]
Excellent advice all around. I would just like to offer one possiblity. If she has learned to associate the word "come" with less that desirable consequences you might want to use a different word when you are training the recall command. It doesn't really matter what it is - as long as the dog learns what it means. Think of it from the dog's perspective. She is having a blast playing in the back yard. She is a high energy dog that needs to burn off some steam. You call her in and all the fun stops. Do you really blame her for not wanting to come in? How would you feel if you were having fun playing baseball or dancing or something like that and someone made you go home and sit in a corner. Would you then try to avoid the person the next time you were out having fun?

Also if the normal treats aren't working - up the ante. Get better treats - pieces of hot dog, chicken, roast beef, etc.

As far as a Gentle Leader - I think it is a great tool, but it is only a tool. It will never solve the underlying problem.
