I'm new to this forum.
My name's Chris, and my boy Philly is a 4 year old chihuahua/maltese mix (malchi).
He is nice to me and my family, but not to anyone to else. Whenever someone comes over, he'll bark and chase them for their whole visit. Whenever I walk him, if anyone (dogs, humans etc) gets near us, he'll run up to them and start barking, making my neighbors annoyed and causing other dogs problems.
I tried obidience classes, but they didn't help with the aggression. I was thinking about hiring a Bark Busters Trainer, but I've heard some bad stuff on this forum about them.
Does anyone have experience with aggressive dogs? Can anyone help?
Oh, and if you know any good trainers, I live in Blue Bell, PA.
Thanks!
