I have an embarrassing problem, Rupert is 16 weeks and still will not walk on lead. He may take a couple of steps and then dig in the heels and point blank refuses to walk. People in the street comment on how 'tired' he must be with the little legs he has, we all know three steps cannot wear out a chi!! He walks so well off lead and loves running up and down our paddock, yet clip that lead on and he refuses to co operate! I have tried coaxing with treats and my vet suggested cream cheese on a wooden spoon for him to follow. Has anyone else had this problem and do they grow out of it?
