Teddy does pull quite a lot on the lead and I have read about this one, but before I splash out, I just wondered if anybody had any experience of this type? There are so many on the market these days.
That looks like a serious piece of kitI have no experience of this harness but have used similar.
I have used and advise the Mekuti harness which also has a 30day money back guarantee. I have had great feedback from them (including a LOT of veterinary staff with pulling dogs!!)
They come in nice colours too- i use the collars and leads for my lot
