I have 4 dogs that come and go into the back yard through a doggie door as they please. They are constantly finding something that needs to be "chased" away. My goats were nervous at first but now if I let the goats out to forage, they will not go so far that they can't see the dogs anymore. If the dogs bark when they are out they run towards the dogs in the fence and look behind them. When the dogs stop barking they will go back to browsing.
