Thanks, McMouse ! There used to be a story that they were originally bred to be eaten.If true, it's not something that chi breeders mention much!
Apart from anything else above (all true and valid points about inexperience, her age, complications etc) is this a dog bought from a proper breeder and registered with the Kennel Club? The original breeder is likely to have put restrictions, in an effort to stop you breeding from her at least without their consent and approval as to sire. (Of course, you may not be the type of person to neither know or care, but it's a point)
This is not beginner's territory.The fact that you ask, rather than having contact with the breeder or breed club who would know you or the breeder, is quite disturbing.You really ought not to try.You don't even know how many pups the breed throws, a degree of ignorancce which is frightening, and itself gives the impression that you see this (utterly misguidedly) as a way to quick profit, regardless.
