I kept her away from him until he outgrew the whole peeping thing....
But that is the whole point, isn't it?
YOU as the owner kept the dog away from the peeping child. You did not yell at the parents to get the kid inside because Abby was scared of him.
When I first read the post, I had mixed feelings that the owner was just trying to warn neighbors "just in case." And that she would do everything she possibly could to contain the animal. Because, as we all know, dogs can be sneaky creatures and accidents do happen. I at first thought that maybe she was being proactive and letting neighbors know that if an unusual occurance should happen, to be careful.
However, after reading C.Ann's further posts, that she was yelling at neighbors to get inside while walking a dog, that the dog has already been loose, and that it does not seem that she is taking any extra measures to protect the community from this animal, then she is not being a responsible neighbor, but a very irresponsible one.
From what C.Ann has told us, this lady does not feel in control of a vicious animal while walking him. It is totally unreasonable to expect your neighbors to stay inside when you are walking this animal just because the owner cannot control him.
Definitely check with a lawyer to see what the vicious dog laws are in your county. Your town may be small, but their may be broader laws.
In many counties, harboring a known vicious animal is against the law without a proper enclosure. In my county, a dog that has bitten before has to be kept in a chain link enclosure, the bottom buried a certain depth in concrete to prevent the dog from digging, and a secure top to prevent the dog from climbing over. When the dog is not in the enclosure, it must be muzzled at all times.
Because you have that note (do not lose it!), please contact a lawyer and see what your rights are.
At the very least, this dog should be muzzled at all times if the owner is that worried about it attacking.
And check online to find any Great Dane rescues that may be near you. Start calling any and all. Usually, these rescues will know of biters. They should help you find out where the neighbor got the dog. Then contact that rescue and tell them you will take legal action against the rescue if something happens to a neighbor, as they approved a placement with a person that admittedly cannot handle the dog. I bet that rescue will be picking up that dog so fast!
