As a breeder I will say you will not be invited into my breeder area of my home, any disruption is very unwelcome in that area. However you will get into the area where our pets and babies live to choose your pet. As far as smoke being harmful to your baby I say not unless she was living in a cloud of it which if she is as caring as you say is unlikely. Any new baby should have a wellness checkup done by its new owner, if you cannot afford that you should wait untill you can. The baby will be fine in all likelyhood
