Didi's only 9 months old, but she's gotten intolerant of male puppies. She's ok (if a little timid) around most dogs at the dog part; she loves white pitbulls and boston terriers, but there's something about male puppies that makes her really scared. She tucks her butt in and tries to get away from them and finally, if they don't leave her around, she stripes, snarls and barks at them. (She has a really shrill, girly bark.)
I'm not sure if I should try to stop this, or if I should let her figure it out on her own. Maybe she needs to be able to establish her space around overly bold male puppies? She doesn't go after them... I'd rather her just be calm.

What should I do? :/
