a yapper is this trait hereditary ?,plenty lads come up with their own conclusions on why a dog may become a yapper,not fit enough,that type known for it,entered to early the list goes on etc but is it more likely that a litter from one will more often than not produce another,never bred a litter myself but would want as close to the best i could find as possible and one that gave tongue no matter its working capabilities just wouldnt suit me although completly understand that some lads can put up with it after all you prob had it over a year till you find out and might not be keen to get rid
