He's a really quiet black lab. I never, ever hear him (I'm in a semi and he lives on the other side of the shared wall). My neighbours are a lovely young family. I think they are out. He has free access to the garden. I'm starting to worry for him, but I'm not a dog owner so not sure if non stop barking from a dog who is always really quiet is something to be concerned about? YABU he's fine, just having a rare barky day, YANBU something's up with doggo.
