@lvoss:
There are also some very good harnesses for loose lead walking without the issues of neck injury. My 14 year old uses the Wags, Wiggles, and Whiskers Freedom Harness because he has a bulging disc. When clipped in the front it acts as a no pull harness. Clipped in the rear it reduces pulling but doesn't really discourage a determined puller. It has been wonderful Nicky as it has eliminated the stress on his neck. Also, the company will repair chewed harnesses. Nicky has not damaged his but we have had many people with dogs who have.

An issue I had with the Gentle Leader was that though my dogs did not pull with it on, it was because they clearly found it aversive and shut down.
thanks for the link, i like the look of the harness . If clipped to the front do you find it realy works to stop pulling ?
Our two aren't keen on the gentle leader and try to scrape it off from time to time. I however don't feel it is causing them too much stress and it certainly doesn't hurt them. I am hoping they get more used to it as time goes on. The results have been dramatic and a lot safer, ie no lunging at traffic or in Kwame's case other dogs. Will keep an eye on them though and will bear in mind what you have said, thanks.
