There's no doubt that over the years and despite every effort to have them on top quality feed etc., we had bitches who would give 'their all' to their puppies and come off the litter looking decidedly moth-eaten - and carrying less weight than normal. Just at the time when prospective owners are viewing too!! Although you might check with your vet, who might manage to sell you some vitamins (lol), I'm afraid it's just time, and again keeping her on her normal top quality diet and exercise.
I can't remember the exact time it took, but for sure, for the most part something like Crufts (or any other show) is off the agenda. I have gone back into the ring occasionally, for a more important show (like Crufts, or the Breed Club shows) but for the most part, my brood bitches were retired from the ring before taking up their new careers.
