The puppy sounds like a lot of fun , he's probably worth a few yard plants
Im sure he knows how to do the grab and shake, it's pretty instinctive. Catching ducks is probably his real specialty though
we had a mostly lab and remember dad tried shooting a duck on our lake for dinner and as soon as he fired he was in the water and had the duck right at his feet just like he was intended to do, without any training.
Mom cooked the duck and no one was hungry, we decided to keep it to fishing
we had a lot of yellow bellied marmots and rats on the grounds. He'd corner one down a hole and bark until a shot was fired in the hole , then he'd know if it was dead he could smell it. once it was he'd walk away wagging and sporting a big doggie smile on his face.
He'll need some training and time, I bet hes like a 3 year old kid now getting into everything with excitement and vigor. Labs are so smart and they always seem to know when to protect and remember who is familiar to them even if there is lots of time between. they will protect if they smell the owner is scared, they can sense it. but unlike a lot of dogs, they are smart enough to know to never to turn up the defenses when it isn't necessary and almost always are very friendly and trustworthy with kids and friends. Beautiful animals.
