WHO'S A GOOD BOY?!?! YOU ARE!! YES, YOU ARE!!!
Check out this AMAZING video of a crazy athletic police dog JUMPING THROUGH A BROKEN GLASS WINDOW to apprehend a perp ... and man, wow.
Here's the deal ... cops in Fontana, CA were involved in a vehicular pursuit of a 31-year-old man suspected of stalking and attempting to injure his estranged wife.
Multiple law enforcement agencies were involved in the chase -- which eventually ended in Corona, CA ... where cops used a pit maneuver to stop the car.
A standoff ensues ... and this is where things got crazy!
