Do you mean Tellington Touch or TTouch? I have used it for mouthing pups or adolescents of both breeds, particularly the rescues. It helped. Also is good, NOT the mouth, for freaked out dogs that just came into rescue, or to relax a dog in general.
TTouch is also good just for teaching the normal pup to accept showing the bite, going to the vet, stand for exam, etc. I actually had forgotten the book I have sitting gathering dust on a shelf. I used body work with dogs rehabbing from injuries, too.
