Do you meen the ferrets?,but saying that they all do.Have used my ferrets to break a few pups as they don't just go for the pup but will give them a nip if needed.Socalizing animals is very important i feel so i do get mine meeting people and livestock as much as i can,my ferrets do meen as much to me as the dogs so i would not risk them with a strange dog or use them to break a adult dog who is a little to keen when they see the ferrets through the wire of thier court.I'm in Norfolk mate not far from Diss.
