Hog dogs get hurt. Plain and simple. Dogs routinely have hogs cut the piss outa them, beat them up against trees, cut them gut them and generally be unpleasant with them and yet they still go hunt hogs. If all the pain that comes with being a hog dog doesn't break them from running hogs, how is a shock collar gonna break break them from running deer?
Of course they can work, but the key in my opinion is for the dog to know for certain it was you who hurt them and it was becuase they were doing something they shouldn't have been doing.
I'm not saying don't use the collar, I'm saying also make sure they know that you know what they were doing AND you were displeased with them for doing it.
for years I saw it your way...but over the years I have changed quite a bit...

I didn't make myself clear...I am talking about breaking pups...it is very important we don't make the big mistakes early on because it will be a setback...but what I write are my opinions so I see it as right but there are quite a few more ways to skin a cat...
I like the path of least resistence and nipping the problem in the bud...just like training a dog to not be afraid of gunfire...it is harder to break a grown slightly shy cur dog to not be afraid of it than to start shooting a few blanks around 5 week old pups at feeding time...and then doing it at the right moment is important as well... 3 or 4 excercises is all they will need but blanks are cheap...and then shooting a big boar over them at ten months won't be a big deal...
