Puppies! We all love them, but some people can't commit to having a dog at home due to time/space restrictions. Now, dog-lovers who want a pet but can't commit to one full-time are finding relief from their yearnings by sharing and/or borrowing puppies. Interestingly,animal lending is nothing new, as this magazine article from 1953 shows, but we just hope that the dog's sanity is OK. [WSJ & Modern Mechanix]CuteFolio" />
