Hi What type...oh well bought it from our local PetsMart pet shop..it is adjustable..it slips over his head and front feet and then clips around his stomach...it wasn't expensive but seems to do the trick..and will adjust more if he gets fat lol..

..
He seems o.k. with it on as well...at least he is n ot pulling on his neck anymore...as he does get excited when out walking...actually I usually have to tempt him on the way out..and he pulls when he knows we are on the way back...!! Aren't they funny...
