Milo and Maisy LOVE to play together. It's very obviously play and not aggression but...when do I worry? Milo is bigger (14lbs). He can get her whole face in his mouth. I do have concerns that he could damage her eye. He also tends to get her around her throat. It's still obviously play because he'll lunge and let go, run and play bow but then he gets her by the throat. I just don't want to damage their budding relationship but I also don't want her seriously injured or worse.
