Hi - I brought Jasmine home at 8 wks., which is fairly standard for chis. Some breeders like to keep them till 10 wks. but I think the main consideration is the health of the puppy and its size. I have heard and read that the really tiny pups should stay with the mom until at least 10 weeks.
I prefer the wire crate for inside the house, but that is just my personal preference. Then I also have a smaller soft sided carrier that I bought primarily to use on the plane. I also use the soft carrier for vet trips. It has a firm floor to it, with soft padding on top and mesh sides for ventilation. Good luck with your puppy-I know you are anxious to bring her home!
