i also have the same problem with samnie. she gets too excited around other people. we go to my parent/sibling's house and she just dashes out of the car. we go to the pet store, puppy class, puppy playtime and same thing. i can't make her stop and she will just pull harder when i try to pull her back.

even when we are out for a short walk, she sees a human and pulls me towards her/him. i bring treats but it doesn't always work.
some say it's a puppy thing...she's 6 months now and it hasn't changed!! is it really just a puppy thing?
