I have a jadge terrier and he his great on coons and also on bears. He is always right with my hound dogs.

Dogs slick tree because the tree still has the scent of the coon in it. One could be okay but 10 is just ridiculous and obviously those dogs don't know what to do.

sometimes dogs like one animal more than the other and they care more. But I would have to agree with Perky's second idea. Tie him up away from the tree and get him siked up from there and yes he will realize that it is good to tree more that one animal
