We've had two really big breakthroughs with Brodie. Last night, my husband was able to get him to go poo while walking him. Up until now, Brodie would only do that for me! Then, this morning, when I had Brodie out to do his business before dawn (we have to rise early on the farm) we ran across THREE different rabbits and even though he saw them, I was able to give him the 'leave it' command and he just turned and went back to his business! No tugging or yanking or whining!  I ended up getting a step in harness for him and it has worked wonders with him. Instead of him trying to lead me around with it, he responds to just the slightest tug on my end and when I kiss to him, he goes my way. I am super thrilled with his progress!
