Too me from what I seen if you put a young dog with an older dog they'll learn. Especially if they come back and your not happy and you let them know. My buddies dogs not too have as much bottom from what he told me but the more they hunt with my buster dog the longer they'll stay with a hog now. I think if you get dogs young enough and put them with a dog that has that bottom that it'll teach them. But then again it's also gotta be in the dog too want too go. And have that drive. JMO
That aint no lie soon as I started hunting ammo and gunner with buster it got to where you might not see them for hrs if they are on track. Used to they would take out a mile on a chase and come back but now since ive ran them with buster numerous times they will stay hooked alot longer even when i hunt them by thereselves it is starting to stick with them. One is 2 and one is 17 months and they are getting better and longer range every hunt.
