Nipping

Holy moly! What age does it start to slow down. I have a 14 week old and he gets what I call “crazy eyes” and just becomes a terror. Non stop biting me and my older dog. I did my research and knew what I was getting into. I schedule naps, redirect here, yelp when she bites, all the training you can do. I just was wondering what age your dog got better with the nipping? Attached is a some pictures of the velociraptor.
