One of the continuing requirements for licensed dog breeders is microchipping the animals on the premises and of puppies before they are moved off the premises /sold on.
Un o’r gofynion parhaus ar gyfer bridwyr cŵn trwyddedig yw gosod microsglodion ar yr anifeiliaid ar y safle, ac ar gŵn bach cyn iddynt symud oddi ar y safle / gael eu gwerthu.
