Let's say there is a dog that has shelter and food and water, physically very healthy, friendly towards people (at least some), physically not abused, but never receiving attention from a human beyond feeding (no walking, playing, socialization, no contact outside of feeding, etc.). Imagine, say, a dog locked in a room, yard, shed, that is given food and water and space to move around but nothing else. I actually have two questions:
Informally (or formally) does this qualify as abuse of some type? If so, what is it usually called? The term "neglect", in official channels, seems to connote physical neglect rather than not meeting the social and psychological needs of a dog ("that dog is neglected" -> "no it's not, it's got food and shelter and is in great shape"). The phrase "emotional neglect", fair or not, always seems to immediately trigger eye-rolling in discussions with folks who don't take the issue as seriously as I'd like.
If so, what are the typical signs and behavioral patterns of a dog in a situation where they are physically treated well but never given serious attention? Can I identify these animals with long term observation? Are there definite red flags that indicate a very high likelihood that this is happening?
