I have a 13 mo. old blf that has absolutely excelled in training thusfar and had been running cold blinds pretty well, particularly for her age ... however over just the last week or so she suddenly has started to refuse to take a direct over, oftentimes just sitting and staring at me. It began on disciplined casting on returns if she cheated cover, I'd have to walk out and basically walk her through the over (on a side note, she will take an over disciplined cast for other people running her, its like she has this overwhelming compulsion to just get back to me with the duck no matter what, however she'll take a back/angleback disciplined cast fine for me), and now it has begun on just general overs. I think I've just been trying to run her too tight for her age perhaps, at least thats the only reason I can think of that would have initiated this behavior ... she just doesn't see enough actual overs except when we play the baseball games in the yard, which she and I have both probably grown tired of since its an every day or 4day a week min. type of thing. The only thing I can think is to just revist T work and/or do a lot more walking baseball with her maybe ... anyone have thoughts on other possible solutions?
