Reading between the lines here. This nonscence has little to do with the breed or the excuses your breeder is offering and much to do with a permissive owner. Anybreed will do this (to differant levels) if this sillyness isn't delt with in wks. 8-16 I don't know you experience or abilities. So, I would tell you to get a private trainer to help you. Personnaly, I would "faith heal" heal this snotty pup.
