Shadow is 77 pounds of “who are you and why are you looking at me?” for about the first five minutes. After that, you’re stuck with him: he sits on your feet, scoots closer if the petting stops, and hands you his paw without being asked. He’s potty trained, begs politely, and believes the garden hose is the greatest invention of all time. On his day out he worked the pet store like a politician, greeting every employee in the building, and at bath time he climbed back into the tub for a second round. His previous owner says he did well with her 6-year-old, too. He’s been waiting since April for someone willing to go slow.
