Here’s what I do. Not saying there’s not a better way but this works for me. I don’t take a dog until it’s at least 8 months old. I don’t do anything with them but let them be a puppy. I have found no simulated activity that has benefited the process in any way so mine see their first coyote on stand. As far as when to go I like them to go when they see one. When you think it’s time to bring the dog back tone him. After a couple you probably won’t have to tone them very many times after that. If you’re concerned about your dog getting hurt you probably won’t make a good dog. You have to let them work and occasionally they get banged up but that just comes with the territory. So the bottom line is pour coyotes on them. They either will or they won’t.
