I'm about to invest in a good deer tracking dog. I am color blind and have a terrible time finding a blood trail, much less staying on it when I do find it. So I think I may break on down and get one. Any of ya'll have any good ones? What breed do you think would be the best at this? I am a veterinarian, and I have heard of several breeds that are used from beagles to daschunds to labs. Want some info before I break down and get one.
