So we have the opportunity to get a free Landseer Newfoundland. This was our first choice of dog when we started our search, so it's kind of exciting. Of course there is a catch. They bought her at a pet store, which means she most likely came from a puppy mill. Do we take the chance and get a dog that might be messed up health wise later on? Would it be ok to ask them for the "breeder" name and info on the papers and copy of the last vet records? Seems a bit overkill for a free dog, but I like to be as informed as possible about big decisions like this.
