Breaking Coyote Hounds From Deer

[CoyoteChaser]

I know this is a topic that’s talked about a lot but I got some young dogs and was wondering what you all do to break them from running deer. I know people use training collars but not sure what age to start using them on them. 1 year old runs a l out of deer and 3 year old hits once in awhile one one. Thanks In advance.
