These dogs had a very intense barking match, but it looks like their bark was much worse than their bite.
The large dog on the left seemed very eager to face off with several smaller dogs on the right when this green mechanical gate was closed. The dogs on the right even poked their heads through the rails of the gate in a threatening manner, and they were all in the midst of a barking frenzy.
Slowly it became obvious the gate was opening, and their opportunity for an actual clash was at hand.
Suddenly, the dogs all hilariously turned tail and went their separate ways like nothing had happened. They probably made a very good choice!
