Starting Pups In The Woods

Hello I am fairly new to hog hunting also I have been hunting for about 3 years and been training and buying dogs and finally got my pack together about a year ago. I started my pups when they were around 6 months old. What I have found that worked for me is letting the pups get to know your older dogs. Then send your older dogs out to hunt and keep your younger dogs on leashes or where they can see them leave out to hunt. Do this maybe a couple times and your pups should go with them but they usually won't stay gone as long but that should come with age and experiance. If we lived closer we could defanantly hunt together, but I live in Oklahoma.
