I have a high energy dog that's very easily distracted. I want to start doing exercises that will make him focus on me even with distractions around (eventually).
I am reading a book and the first exercise suggested there is to make him touch a target (my hand e.g.).
But I was wondering if there aren't any better exercises out there. I don't necessarily mean more complex. It's just that I don't see how touching my hand will ever be useful.
So: what are good focus exercises for a dog with a lot of energy?
