Took my Welsh Section A out for a walk down the country lanes, which are quiet but to do that we have to go along a quite busy road and this is where the problem is. He gets totally freaked out, he rears, stands on me, barges me, prances about the place, all in all he just gets very difficult to deal with and its gets almost quite dangerous although I do manage to hold him. What I wanted to ask is: How do I deal with this? because I need to get him used to the lorries, cars etc Thanks
