I think slip leads are great but where we live now I stick to a headcollar. There is so much crap about and so many things going off (aggressive dogs for one) that I'm worried if I dropped Rupert's lead and he ran off and got caught, the slip lead would yank tight on his neck and do damage. Where we lived before he walked fantastically and I had no worries, but round here there are a fair few dogs you don't want to be within 20 feet of at any cost, and there are a few Rupert has tried to get away from and its easier to gain control by a headcollar for me. On his slip lead he has had me over a couple times trying to get out the way of certain dogs and its not good for his neck or my arse
Rupert walks fine on a Canny, he has never quite been to heel he has always been about 9inches to a foot away from my leg which I'm lead to believe is too far, but he doesn't physically pull and is responsive so I just leave it now, I think that might be how it feels most natural to him and because I have a habit of stumbling he probably fears I might barge into him
I do like the Canny collar, its like the K9 bridle and doesn't ride into the eyes, Rupert was useless in a Halti just didn't work for him at all and he could get it off easy as pie.
Its very frustrating having a dog who pulls, we got Milo at 16 months old and he pulled like a train so it was straight into a headcollar for him because despite being only 27kgs he can yank me pretty damn far and I'm not short/small as such. He was harder than Rupert hands down but did get there. I think it really is persistence and lots of time.
I really wanted to get Rupert back on a slip lead this summer but with the sorts of dogs round here in regular every day walks its just not worth it
