Yikes! It sounds like this guy has some issues. I agree, why wouldn't he be walking on the other side of the street if he didn't like barking dogs...or why even walk around in that area in the first place? Is this a resident on that street? It seems very odd to me that he would go up to the fence to yell at the dog. Of course the dog is going to bark if the man is on her property!! Taking pictures is also very suspicious, not to mention an invasion of privacy. I would definitly talk to the authorities, and mention that this man has been harassing the dog and taking pictures of the property as well as other people's property!! It definitely is the owner's business!!! The man was way out of line when he said that it wasn't. That way the authorities will be aware of the situation and could give some advice. The owners have tried confronting the man, but he wasn't responsive. The dog is properly enclosed in a backyard, so the man has no reason to be instigating anything from over the fence. That's really too wierd! Yes, I would definitely keep Belle under extra supervision, but I do recommend calling the authorities or a local animal rescue to see if they have any advice to give. The owners and the dog aren't doing anything wrong to instigate this man, so I would be really cautious about the situation. Please let us know what happens!!
