Classic case of hierarchy. The ole struggle for dominance.
Lay into em with a cable leash and see if a lil skull dragging cools their heels.
As stated above .......if they are worth their salt.......their gonna be hard headed and mean as sin.
If your talking bout cur dogs.......just build you a second pen......its easier than trying to get them to Dr. Phil for manner lessons.
If it boils over to the woods after you have softened their heads.......hunt them separate or get ta culling.
I always enjoy reading what Myles has to say ! He's what I would call a Redneck Oracle ( for those who know what an Oracle is

) haha . I would split them up but just in case you decide to cull one. From what I've observed after raising a few , the less dominant dogs usually make the better hunters. They're more worried about hunting than fighting.
