i walk three dogs a night. I have a problem mainly with Mazie. the walks are not enjoyable for either of us. I use a choke chain and I am resorted to a two ft lead but she's got a thick neck. All three dogs are suitable for comformation, that is they do well in the ring with the little show collars on. I put a little shiney show collar on Mazie and shes a gem. problem is I can't walk her thru the neighborhood with this particular chain, should I use a prong and do you purchase two inches longer than neck size like choke chains.
