Is this a fishy dog adoption?

the only way to find out is to go see the dog and the family and make your own decision after. take someone along who is familiar with the dog breed so they can evaluate the dog, and see what the home looks like and see how the kids act with the dog. If you decide to get the dog, get the papers, ask for copies of his shot records from the vet, and get a bill of sale from the owner. if he is not willing to do any of these things then don't get the dog. if the man is legit, he should try to do anything and everything to find this dog a loving home.
