hutchster said "Have you tried talking to the dogs in a calm voice each time you walk to the box ?
Just strike up general conversation, asked them how they're doing, hows the weather, if they have plans besides barking at you, what it must be like living with their owner.
It might help familiarize you to them and you could end up becoming their friend, the owner does sound like piece of work though "
the dogs can not get near you to bite you they are in their own yard am I understanding correctly ? it's just the barking that is annoying ? I would rather put up with the barking rather then if it was a biting thing .sounds like the owner enjoys letting her dogs out just to see what they do for her it's entertaining nothing better to do .
as far as treats that would be a no no for me the dog owner would probably not like that .
