As a lifelong dog owner (and animal lover), I suggest the few seconds of video posted on social media and news stations may not tell the entire story.
All dog social traits and "personalities" are different. I have owned dogs that would hunch up and turn tail from my facial scowl; consequently I have owned dogs that would require a tap on the back side to get compliance.
A dog that is trained to chase and subdue humans especially needs to obey its handler. I did not see the officer "hit" the dog as reported, rather I saw a tap on the ribs. The issue of picking it up by the restraint is different, but all dogs are different as to their compliance level.
Maybe it was abuse and maybe it wasn't, but all facts should be known before any judgment based on a few seconds of video is conclusive proof of anything.
