Most, if not every hound that I have owned has had to be broken off of deer. I primarily bear hunt and run a few bobcat and coyotes in the winter. The method I use, which has worked well, is a sound scolding and thrashing or shock collars. Same as giving a child a spanking. And there is the same line as with children where it goes from punishment to abuse,(I am sure there are those that will disagree with this method but it is affective).

Here me out before you think brutallity on this next part.I use a plastic bat for the whoopin. The reason for this is that they sting a bunch but don't bruise, and they makesomenoise. The dog will fear the bat and not you.Do your traingin early onin the dogs life, that is when it's the easiet to for good habits.

Find a deer, dead or alive and put the dog on the scent. If he so much as wags his tail at it let him know it is wrong, verbally and physically, you have to make sure he smells it though. And vice versa find a fresh bear track and walk him on it and love him up while you are doing it. Pet him until your arm is tired. Just keep at it, don't get frustrated with it. It all takes time, and some dogs take longer to figure it all out when some pick it up the first time you hunt them.
