There is a difference between a dog that will bark at something it can see in a tree, and a dog that that will trail and locate, and bark treed on something that it can not see. By scent only.
I have seen several "tree dogs" that wouldnt tree a lick. Ive seen them watch game go up a tree, and not tree.
I dont believe every dog is a natural tree dog, i do believe that most dogs can be "trained" to tree.
we had a red tick that would sit and watch coons, never heard him bark unless someone was in the yard
