I hunt mainly on woods cattle(angus/brangus) properties... cattle have free range to go deep into the swamps...
Always fun when a lone 300# black bull calf jumps out of the bushes, way down in a bottom, in front of young dogs the first few times....
I try to just keep putting a dog in the hogs and hope they don't decide to go cow dog on me
.. but when I do have one that gets too interested in cattle, I will fry him on the max setting once or twice just to make a point.... other than that, I don't care to use e-collars at all.
If that don't work, they go to the cowboys!
