We've thought it might be due to the military helicopters recently since they're training at this time of year, but he barks even when there nothing. It usually happens when one of us are in a room with a giant window with a view to the street (he frequently barks at people out there, but theres no one when he does it now) and we for the life of us cannot figure out what he could be barking at or if it's something to visit the vet for. Please help or give suggestions if you can, I'm getting worried.
