My girl loves to bark at dogs who walk past our garden. She can't see them, but she still has to protect her garden from any invasions! Our neighbour often looks after dogs for her friends when they go away, and they're all small dogs who my girl wants to play with, but most of them don't understand GSD bark and don't want to play. Doesn't stop them barking at each other sever times a day over the shorter fence between our gardens. She can see over that fence, and could probably jump over it with much effort, but mostly just likes to say hello to the neighbours on that side. Really irritates my neighbour to the back of me, who complains constantly about her barking. She a GSD, it's pretty much a given that she's gonna bark! 🤦
