I agree - your dog may have been abused, just settling in or simply doesn't feel the urge to bark. Were you able to observe your new dog in the shelter prior to adoption? If so, was he barking then?

Some dogs just don't bark much. Mine doesn't, hardly ever. When he does you know it though, he has a big strong bark, of a much bigger dog than he is. Instead of barking, he tends to whine...

btw, congrats on your new addition and thanks for adopting a shelter dog!!
