I got my puppy last week and I named it Lily and I was just wondering what I can do with Lily to play with her. I feel like she gets bored of her chew toys easily, and she'd much rather spend time with me (she's very clingy). Lily is only 9 week old, so she's little. She weighs 4 pounds, and has a small mouth. I want to get her a tennis ball, but I don't think it'll fit in her mouth. What can I do to play with my puppy?
