I have been raising and training for about 8 years . Since joining the CD program (about 3 years ago), training has definitely been easier, but as I am doing my case studies I have noticed a trend that I do not think is coincidence. It appears (at least in the last 3 baby seasons - 18 months) that babies sired by same male seem to have the same degree of difficulty in training. For example - my one herdsire seems to throw babies that are all very mellow and can be trained in one lesson with no issue (love that ). Another one of my herdsires have babies that stick and plant and wont move forward and then another has babies that like to jump and rear and throw themselves to the ground. There are some deviations to these generalizations - but by and large I see a trend emerging. I have had many babies this past year and a half that I have had to train (much more than in the past) so maybe this is why I had not really noticed it before. The thing that is the most interesting to note that the ones that I do have some difficulty with - it seems to ALWAYS be the SAME difficulty, the same issue. Maybe this is something that many already know - but I had my a-ha moments last season but needed more data this season in order to determine if I was reading into it and I don't think I am. I have also noticed (but not as much certainty here yet -need more data) that my girls are harder than my boys. Does anyone see this in their experience or am I in an alternate universe? Rose
