Take into the equation, many Border Collies are hyper-sensitive and will s h u t d o w n if you're even feeling a little bit off, they sense that. Also because they are hyper-sensitive, teaching some obstacles and teaching contacts can take 10x longer than it takes a more easy-going breed. Not to mention, you must keep their focus while working with them, because they can become easily distracted and fixated on things going on outside of the ring. Sometimes that speed is a huge handicap, as is that intelligence, because many BC's have issues with going off on their own and taking the wrong obstacles.
lol that is so true, I remeber doing a regular coarse with Happy, we to do the weaves, she looked at them(she HATES weaves) and ran back to the start and perfectly repeated the begining of the coarse like "there, that should make up for not doing the weaves" lol oh and at her first trial she decided that the table was just a broad jump lol "I dont wanna stop, how bout I just jump it?" hehe

oh and of coarse traning tricks? everything makes her shut down, if you act too upbeat she will shut down, if you act to gruff she will shut down, if you talk "down" to her she will walk away, it's maddening lol
