Why Labels are Not Helpful
It puts a label on the dog that is not helpful to the human, or the dog. It tells some other person's storyline that can get adopted by the human partner, and stuck on the dog. A description label can make the difference between a dog in a shelter finding a home or not; living and not. It's unfair to the dog!
The label makes the human partner feel like they are in a mess with their dogs and doomed to live with a serious behavior issue. Some people will take the label and get rid of their dog because they don't want to deal with it.
Experience with dogs is not education necessarily. Sure, you can learn a lot by observing them and being with them, but that doesn't mean you are describing them accurately. I see this ALL the time. It drives me nuts! It would be easy to attach some kind of story to him and his behavior in that situation, if you didn't know him. Sure. It "looks like",... but that is missing a whole lot of information.
