The Magic Squad and the Dog of Great Pot

For Calvin Hastings, days after school at Alfred Ludlott's house are the pits. Alfred has a big lawn and a dachshund, but Calvin's gifted younger brother, Monk, and his bossy, overachieving neighbor, Jenny, are getting on his nerves! No wonder Calvin jumps at the chance to visit the local humane shelter with Alfred's neighbor, Dr. Jamar. Calvin falls for Train, a big, loud, friendly dog with "great potential." Train needs a home--but Calvin's apartment building won't allow dogs or cats, Dr. Jamar is already fostering a pet, and Alfred Ludlott has Fitz. Calvin's ready to give up when he finds out that Train isn't the only one with "great potential."
