It's funny - I have one dog that is very sensitive to head touching. He will do anything to avoid it. Season has been posting a lot of Jeff Gellman vids and that was one thing I noticed that he does all the time - taps the dogs he's working with on the head while he's talking to the camera. Just something I noticed and that bothered me a little, only because I have a dog that doesn't do well with that. Clearly the dogs he's working with don't mind. Ella is a hands-off dog as well, but not to the point that Oliver is. Al? He needs a nudge now and again to snap him out of his bubble. I think it's all about knowing your dogs and not assuming that what works for one person's dog is going to work for another.
