This gyp was just as you described yours, really high strung and really lean and athletic and never cycled until she was past 3 years old, and that was this past summer and I stuck her and had a litter of ten, I couldn't get her to cycle once I got everybody else lined out and cycling, I swapped back to showtime 24/20 and started her on a daily k9 multivitamin at the recommendation of a close friend who is our local county agent and within about a month or two of swapping her diet and starting her on the vitamin she came right on in...
