At christmas, we got a papillon puppy. she's the cutest little thing, but every time she sees a random person walk by outside, she growls!! Oh no... we can't let this go on, or people will think she's vicious! she also growled at a neighbor who was about 10 yards away when i took her out for a walk... I'm worried that she will continue this behaviour as an adult. Perhaps it's only a puppy scare phase, though... I need advice, please!
