This may amuse you...
Our youngest collie is 2yrs old now, and is possibly one of the best bred out there (father was international supreme champion trialling dog), sorry, didn't mean that to sound arrogant, she took a year to find and we were so lucky to get her.
She's been a puppy for a long time, initially showed no interest in working, but our trainer had her running round sheep and knowing her commands within 15 mins.
She's always been a bit of Sheldon (for big bang theory fans) - super bright but just doesn't really get life, play, toys etc etc.
Today's classic? She was working in the folds trying to move a bolshy little lamb. Lamb went for her to try it on so what did she do? Yelped and ran to hide behind Daddy 
Oh dear, I guess there's no such thing as breed temperament, is there? Good job she's stunning - there's always the Stupidest Sheepdog class at the local show! (whilst her sister wins the Nursery Trial...)
