Hi! There have been quite a few threads regarding the WYDWL harnesses. I used to use one and was, at first, very enthusiastic, it was relatively easy to put on, compared to the halti for example and, for a while, it did help. However in my experience, it isn‘t a solution long term as it doesn‘t teach the dog anything, and after a while my dog was pulling the same as before but at an unnatural angel and I‘m not sure if this might cause harm eventually.
Humphrey spends most of his time off lead, so I don‘t tend to use a harness very much now. I‘ve spent no end of hours training him to walk on a lose lead with just a collar and for everyday situations he‘s not too bad but if he‘s in the town or a busy place he still pulls, so then I use a normal harness, just to take the strain off his neck really. The WYDWL does have benefits and I must say their customer service etc is excellent but its not an alternative to consistant training, - in my opinion!
