You do what you want to do and ignor OH!!!
Unfortantly more unregisterd dogs do not need to be bred, there are more then enough dogs looking for homes in rescue. You will never know if she is healthy enough because you won't be able to get certain health checks done. Ask your husband why he thinks breeding is such a good idea? Does he like the possibility of losing your beloved girl (also blues are hard to get arn't they?) and the expense if something goes wrong. Only earlier this year, a friend of mine bred a litter, the bitch was healthy, the breeder had bred litters before and knew what she was doing. Unfortantly on the operating table she lost her bitch, but saved 8 puppies, all that had to be bottle fed and everything for the first few weeks of there lives, do you want the possibility of that?
I have to say you are thinking correctly, get your bitched speyed and stop any chance of losing her.
