I have a good friend who is a Tellingtouch practicioner. she uses these wraps all the time, but she doesn't buy the products. She uses old t-shirts and tensor bandages (like the kind you get when you sprain your ankle). Works just as well and much cheaper.

She has worked on several of my dogs. There is no force involved. Not like restraint therapy that is sometimes used on kids.

The wrap gives the dog a very clear impression of where they begin and end, something freaked out dogs sometimes forget! It was highly effective with Ozzy in particular. When I first got him, just touching him was a challenge. Then he wouldn't walk on a leash at all--too scary. With a wrap on, he would walk and walked very nicely. He knew exactly where all of him was. I'm sure anyone who saw us thought I was insane--walking a dog who needed that many bandages on him! But it worked!!! Ozzy is much more confident now and I don't use it on him anymore.

I sometimes think that harnesses work the same way. I have a couple dogs who are afraid of their own shadows, expect when they are in harness. I suspect it's a combination of doing what they were bred for and having pressure all around them to let them know exactly where they are and where they can go.
