All I can say is our labs are so easy to train as they love thier food. Our chocolate one sticks to me like glue on her walks, she joins the others but then comes back. Our 2 young ones are 18 mths and still will destroy my things like socks, pens, glasses, plastic stuff, not taken shoes since they were young. Labs often chew plaster off walls if they get board, also wood stuff like table legs, the closer the strain to working dogs the more board they get but with other dogs and children you should be fine.....usualy they grow up and chew no more but don't hold me to that one!!!!!!!!!! We are very proud of our Labs and your little Chocolate drop looks ace!!!!! Oh keep the pup on puppy food for as long as poss, around 12-18mths as they need to grow good strong bones!!!
