Learning and teaching impulse control on the doggy level is definitely a big challenge!   I recently heard a dog trainer talk about how he had a German Shepherd that he felt was totally in check - no need to worry about impulse control - chase after a cat and lose his life due to an automobile incident.   So, I know safety  must always come first.   And I must always err on the side of caution.  But I've found one thing that Shep loves even more than chicken - and it's working really well for our impulse control training right now.   Listen in and see what I'm talking about here!
