You know, one of the things I liked best about my breeder was that her home had a definite "doggie" smell to it, but her dogs were all bathed, free of fleas and very happy to see us. To me that said that the animals were indeed kept in her house and not in a separate building. Hers were crated while we were there but able to roam free when no visitors were present. I could tell this when I would phone...I would always hear little noises and barks that sounded very close and she would often interrupt our coversation to speak to her dogs...things like get out of the pantry or stop playing with the laundry. I never heard whimpering, crying or yelping. Personally, I don't think that I would ever own that many dogs at one time, but if I did, I would be certain that my house would have the same "doggie" smell to it.
