Newfoundland only behaves when owner isn't watching

Sierra is trying to train her stubborn but sweet Newfoundland to walk well on a leash. Sierra is clever enough to sense Samson is acting out because Mom is overseeing the operation. Once she has Mom leave and hide inside, Samson quickly starts to walk happily with little Sierra. The bond between Newfoundland dogs and children is very strong and they were bred partly to watch over and accompany children. They are certainly a great match and Samson takes his role as guardian and friend very seriously, even though he often gives her a run for her money!
