Hello, How can I deal with my 18 weeks old chocolate lab who urinates on my couch? How should I punish him? Or should I punish him at all? How to make him understand that this is not a right place? I take him out every hour to do his stuff outside but this usually happens overnight when I'm sleeping. I wake up to find the house soiled (which I was ok with giving that I wont be able to take him out in the middle of the night) but not on the couch. Please help!

I have 3 month old chocolate lab who is becoming very aggressive and always wants to bite and jump on us specially on my 8 years old daughter. He nips her with his very sharp teeth causing scars and blood. He always wants to grab us by the feet or torn what we wear. He 's never calm. We take him out, we walk him and I train him using your techniques for obedience and still. We can't roam freely in the house coz of him and we started to leash him now a lot. please help! We are all bloody scars :(
