We use harnesses and they are wonderful. Our dogs are both 55lbs and 70lbs and I can walk both of them by myself with ease. We use the Sporn brand Anti-Pull comfort harness. http://sporn.com/training/sporn-halter/ Used it with our previous superpuller dog, Calvin, for years.... who was also 65lbs. Worked great.

Hadn't seen that kind. Neat.

We were thinking one like this.

The great thing about the anti-pull ones is that it puts pressure in the armpit areas if they pull which automatically causes them to cease. Hence the Sherpa cushions to protect from chafing. We have never used the kind you show above, so I am not sure if they are as effective or not.

On our Babe I had to use ? I do not remember the name, but it
went around the face.
She was such a sweet Babe , she wanted to go and meet every one!
Which I did not !
That worked for us.
