Disturbing video apparently shows man abusing dog and waving a knife around

This is sick… a disturbing video from Florida appears to show a man physically abusing a dog and handling a sharp object… and now the police are involved.

In footage posted to social media by Only in Dade, a man and a large dog are seen on the balcony of a Miami high-rise… and the guy appears to be grabbing the dog by the neck and head, pushing the poor pup's face toward the ground.

The dog here is visibly frightened and tries to escape from the man… but he grabs him again, this time with what looks like a knife in his hand, and appears to punch him several times in the ribs.
