Did the attorney call you back? Because it sounds like you're going to need it. Clandestine meetings are almost always a bad, bad thing. You need to find out if there's anyway to stop this before they have any more public meetings where they try to push an amendment thru.
I know you hate confronting people, but you're going to have to step up and make these people deal with you. You've got a stupid woman with an out of control rat that PROVOKES other dogs who hasn't had a word said to her who's on the inside of the anti-Grace and Lady lobby, pushing the issue.
Besides the trainer, what about obedience certifications? If you can shove certifications in these people's faces, then your claim that your dogs are reacting to provocation should be bolstered.
One of the girls that works on another floor here is on the side of the devil regarding a pit bull in her complex, and that dog's owner pretty much shut the condo association up at their meeting on Monday night by waving the dog's obedience certificates and CGC in their faces. She's been frothing at the mouth about 'that dangerous dog is allowed to go anywhere he wants because of that piece of paper' ever since. You can't even get in an elevator with her without hearing how dangerous the dog is, yada yada.
Do you have any papers that you can wave at your stupid HOA?
