There is no reason healthwise, why your girl shouldn't be mated again this season. Since she's of an apropriate age, and she's not been burdened by a large litter the last time, she should be fine.
Five months between seasons is on the shorter side, but within the normal variation. I understand the reason you want to breed is to have a bitch pup to keep, for showing and maybe breeding. What Brainless said in an earlier post is a thing to be considered. A bitch with silent seasons isn't the best bitch to keep a bitch pup from,for breeding. Or to breed from at all, really. We want our dogs to pass on their own good fertility.
If you decide to mate your girl again this time, it might be a good idea to have a progesterone test done.
Good luck,
Karen
