hey i have a border collie, and he loves to play frisbee. my experience is that you really don't need to teach at all. they do it on their own. my dog since i got him has been able to catch frisbees in the air, return them in mouth (he can't throw them yet

), catch at weird angles and such. just start small and get bigger. they are born athletes, you will be amazed. as they work up they can jump higher and higher. my dog can jump 6 and a half feet (almost 7 feet straight up now) in the air to catch a frisbee in midair. or even jump off my leg or back, bounce back and catch it, or even do a half flip and then catch it in air, etc. he learned this mostly on his own as we went. then take him/her sheepherding to really see how amazing border collies are. you wouldn't think that could be instinct, but they instantly now what to do. truely awesome dogs! very,very, very, very high energy dogs though. be prepared.
