i agree t bob and bryant . seeing what a dog does at a real young age might be a indication of the dog at maturity ... and it might not , i,ve seen lots of 5 months old super stars fizzle into duds by 18 months . ive seen lots of dogs ruined by pushing them too hard too young when they start showing promise . i ve ruint a dog about every way possible.
i don,t wanna raise and feed nothin but the best blood i can get a holt of and i let them run loose as long as i can , when they start harrassing the neighbors stock i put them up . at 10-12 months i work them several times and if they aint shonuff hookin up they are eliminated from the feed sack and the gene pool
