I agree to a point i had and have seen many dogs right off Frisco and his popular son' Rebel Yell, Hicory ect.. alot were very shy and that drove me crazy along with it seemed like the had a clock that stopped at 40 mins lol. So i went away from the line but as time went on i saw dogs bred down thru Frisco from the M.Kelly strain of the line and they were leaps and bounds ahead of the ones coming from the source so to speak. The Young China Boy seemed to add the bottom, the dogs that came about Macguyver,Mojo,Miester,Gr.Ch Goldie, Ch. Pup Pup ect...were world class animals. Also had some very dog Chinaman x Nigerino dogs who lacked nothing all.Just like any line it all depends on who you get them from and why they did the breedings. Yis Ole Man
