So when I finally get my potential show pup I would like to do ring craft classes with him, I have already found a local class and I am going to watch next week. But my question is what is the best collar to start training him in. It seems all the boxers at the shows here wear a long thin choke/check chain and a find leather lead, or a rolled leather slip lead. I have various at home already, I have the nylon half check/combination collars, fine choke chains, rolled leather slip collars and nylon slip leads, and the standard buckle collar. I use a slip lead for day to day walking with my adults and always have done, as when used correctly I find them fantastic. Should I start as I mean to go on, and get the pup used to one type so he knows what his job is, or maybe start with a half choke/combination collar as its more gentle?
