Thanks for all of the great suggestions.
Quercus: I will try opportunistic clicking/rewarding when he is nesting, hopefully it will help reinforce the desired behavior rather than confuse him.
Agilebasenji: Surprisingly enough my guys do not roll on damp towels, very unbasenji like of them. They do insist on grabbing towels, running off with them and promptly killing them by giving them a great shake before stealing the stoled goods from each other. They ignore them during our training sessions because I have taught them 'on your bed' where they will run and place themselves on the area I point at (dog bed, place on couch, towel or blanket laid out) Thanks for the advice.
Clay: Matter of fact we just began targeting on Saturday as well, with the nose touch. Dude does have a great high five so I think that paw touch won't be difficult.
Tonight I began directing him onto the towel and doing a low five and click/rewarding when he would give the five and his paw would land on the towel.
Lvoss: That's what i'll try next as soon as I can get him to exhibit a bit of the behavior. Thanks!
