Before he moved, I coyote hunted with a friend and houndsman for years. He has raised/hunted Walkers for about 50 years, first for fox then for coyotes once they took a foothold in southern Ontario. In recent years he has started using English Foxhounds (which most N. American hound breeds descend from). English and Walker hounds tend to be the fastest of the scent hounds and can occasionally catch a healthy coyote. Even if they don't catch them, their speed puts a lot of pressure on the coyote's. By knowing the territory that you're hunting in and keeping track of where the hounds are, you can get hunters in place to cut off the chase. Getting in place frequently requires driving several concessions to get ahead of the chase. Some hunters do use Redbones, Blue Ticks, July's, Plotts etc- but they aren't nearly as popular around here as the Walkers and English dogs.
There is training required for any hound to excel. Yes, hounds have a natural instinct to work tracks and chase, but becoming proficient at tracking requires a lot of practice. As well, reenforcing the game that you want your hound to run usually requires a few corrections as they may trash onto deer, rabbits, squirrels etc.. And, the best hounds are athletes who need to be kept in good condition- LOTS of exercise, good nutrition and not too much excess weight.
Not every hound makes a good hunting dog and very few become excellent hunters. The more training a young hound gets the better its' odds of reaching its' potential. That said, I'm off to take my 8 month old Plott hound, Wendel, out for a run! With a little luck, the coons are going to catch hell next fall!
