Alexandra - We too have had a similar problem with our larger yet older and arthritic dog doing the pulling on walks- he is the most docile sweet thing and not aggressive in the least- but when he gets that leash on he just wants to GO - somewhere - fast- We too tried many things but also not wanting to harm him in any way- (the choke collar doesnt work on him or the spikey thing or yelling either) - we found a harness that slips over his chest & around the front legs & attaches to the leash at the collar area & that has done wonders! i think the pressure is in the right places to make him walk more conforatably and at a good pace- when he pulls and we tug back he stops immediately & walks - it doesnt hurt him - just seems to remind him to remind him to slow down- Its called Yuppy Puppy Anti- Pull Harness- we got it at walmart i think- There are actually lots of different kinds of harnesses- and i'm sure most are fine.
