Put snap into his collar with some chain so he cant bite it intwo, them take the leadrope and go back to his stomach and put a 1/2 hitch all the way around his stomach, lead him from his belly, he willl figure out the presure will disapear right away when he walks forward, lots of dogs who have never been tied on a chain will struggle due to the natural i am choking from this sttrange thing on my collar choking my neck. Chain em up and them try the 1/2, prob break him in one day on a chain and them one night walking with the 1/2 hitch belly tie especia;;y if he sees other dogs taking off and wants to follow but u have his belly under control.
I agree with the 1/2 hitch if no time for training..works in a pinch...
but if I have the time I tie the dog on a chain for several hours a day for about 3 days and this usually works...at the end of each training course I try to coax the dog to follow me because I have a meat treat or 2...the dog does not have to follow and I use very little resistance on the leash at this time...if the dog follows I take him for a walk...if he is not ready I do the chain trick again...
I also have a metal 3 foot chain with a snap I use. This I snap to the dog and let him drag it around for several days about 2 or 3 hours at a time and I pick it up now and then and see if he is ready to follow...I usually have the dog wanting my attention and a treat here and there and the dog wants to follow and his mind is off the leash...I test to see if the dog is ready again...if he pulls away I continue with the training...I never force the dog because it takes a little longer that way and the dog then develops fear toward you...something you really don't want...usually takes from 1 to 3 days to have the dog broke to the leash...
