When Naja drools on people, I tell her it's how she say's "I love you."

My
BIGGEST issue, is the people who approach Naja and I without asking permission. Naja has aggression issues when approached like that, and I can usually tell if it's gonna be a "sniff your hand and let you pet me day", or a "don't come near me or I'll freak" day. Or people at the dog park that will approach her for pets even when she's barking at them and backing up, with me saying "She's really not in the mood right now, I don't think you should come any closer". One lady tried arguing with me telling me "No it's alright,
Dogs Love Me" Well NOT this one, not right now. I had another incident with a mentally disabled person one day. We were making our rounds and a guy who looked 16 approached Naja, he was wearing a hoody and sunglasses, and she couldn't see his face, so naturally she started barking and ran away. This guy starts laughing, and CHASING her!!! I'm running after him telling him to back off, not knowing his name I'm calling him "kid". His caretakers, got mad at ME! Saying he's "not a kid, he's a full grown adult, and his NAME is ...". So I told them I don't care how old he is, to get him away from my dog or I'm afraid she's gonna bite him! I'd bite him too if he were chasing me around like that when I'm scared.
