I have a four year old dog that I just started doing hunt tests with about a year ago. I duck hunt with him a lot and train frequently and he has almost no obedience problems during those activities (he is very steady, doesn't creep, never breaks, always walks at heel with no issues etc.). However, on his third hunt test which was about two months ago, he started becoming overly excited in the holding blind. Last weekend we were at an HRC test and he was trying constantly to peak around the blind or look underneath and was so concerned with seeing the birds that he was even trying to get free of the leash even when I told him to heel. I was so embarrassed and haven't ever experienced this with him before. However, he is fine once we leave the blind and walks at heel all the way to the line, but I am concerned that eventually his excitement will get the best of him and he will lose control going to the line as well. I want to fix the problem before it gets any worse and I thought I would see what advice you guys might have to offer.
