Hi All. I need suggestions on games to play with our 4yo Boo. He doesn't like tug nor does he play fetch. He loves to chase but then tries to knock us down and bite our hands. He doesn't bite to hurt, more just holds but it can hurt. We go for walks but they don't thrill him either. He's smart and I love to find ways to stimulate him. Any play suggestions would be great, thank you.
