A terrified jogger was forced to scale a fence after a pitbull broke free from its leash and chased him down the street.Shocking CCTV outside a home in Wicker Park, Chicago, showed the dog lunging at the man as he ran past him on the pavement.
The animal then slipped out of its muzzle and leash and started aggressively jumping up at the jogger while its owner struggled to get it back under control.
At first the man tried to shield himself with his arms, before he resorted to climbing the fence behind him.
He could then be seen sat on top of the gate on his phone as the owner still frantically chased the dog on the ground.
At one point, the pitbull ran out into the road and appeared to start barking at another person with their car door open.
Give him the exercise he needs. All pets need regular exercise to stay fit and to release their energy. Without it, your pet will begin to act out. Young pets that do not get enough exercise are more likely to develop negative behavioral issues that lead many to give up their pet.
The dog was still not back on the leash by the end of the short clip.
The jogger, who had jumped down from the other side of the gate, could be seen pacing inside the garden while on the phone.
He suffered several bite marks to his arms but did not press charges against the woman.
