I am not European, like the vast majority of YT members, I'm from the "Good Ole US of A" and from the DEEP SOUTH where etiquette and good manners mean a lot. I wasn't particularly offended by your post simply because I stopped reading after reading the second paragraph. I opted to post anyway
Anywho, if you DON'T want advice from non professionals, I would strongly suggest that you let go of a few EUROs and hire a professional. Most of us here at YT are very intelligent, very devoted Yorkie lovers who have learned from the school of hard knocks and from our YT family. I have learned more here from my YT family than I have learned from the professional trainers -- who have lightened my wallet by many $$.
