My neighbours dog (Street of semis, but not attached to me) has been barking since 9am this morning. It's not a frantic bark, it's more of a woof woof... Then a few seconds later woof woof... But its constant. She isn't home as I've knocked on. My mind keeps jumping to horrible conclusions. Should I do anything about it? Not that I know what I can do! I just think it's so warm today, how could the dog even have the energy to carry on barking for so long?
