With all the variations of dog sizes, from a poodle to a dane... If we were to find these bones (say they were millions of years old), would we conclude these are different species? What conclusions would a paleontologist make?

Initially, yes. Single species never have the type of variation found in domesticated species where breeding takes place, and dogs breeds have a huge amount of diversity.
  Eventually however, future scientists would find morphological constants that would tie them together. Then they would try to hypothesize about why there was so much diversity, although it would be very hard to pin it down unless they realized it was done deliberately by our species.
