Some other article under that one mentioned a back injury.
Not sure what that has to do with a little pocket dog, though.
I have a "pocket dog", well, really it's more of a backpack dog (9 pound Shi Tzu-Maltese mix). That thing is certainly not an "emotional support" dog. If anything, the darn thing is emotionally draining. It's like it has a switch that goes from comforting to wildly insane, with no middle ground.
