Why does my puppy...

[Happymm]

bark at other dogs so much? She's a 15wk old lab, is a complete bitey PITA. Now has started barking madly at other dogs. She's well socialised so it's not that she's somewhere new or seeing new things...

Also tonight on walk started growling at a young girl who was going to pet her, as if she was a crocodile or something...

She sounds anxious, or scared. I think it's quite common to have a sort of fearful regression?! Try asking new people to make the puppy sit and give a treat perhaps? I do this with everyone who visits the house, including the window cleaner and postman!!
