POMPANO BEACH, Fla. -- Two men are charged with animal cruelty after a United Parcel Service's driver said he saw the pair abusing a small dog.

UPS driver Glen Delong told police he was working his route along the 1000 block Hammonville Road in Pompano Beach Wednesday when he spotted two men throwing a pit bull into a canal.

Delong said as he watched, one of the men hit the dog with a stick in an attempt to keep it submerged in the water.

Delong called 911 and said he watched the abuse continue for 20 minutes until deputies arrived. He believed the man was trying to kill the pit bull.

Jarrius Flournah, 18, and Reginald Robinson, 19, are charged with animal abuse and trespassing. Police said Flournah picked the dog up by its collar and dangled it in the air for about 60 seconds before throwing it back in the water.

Robinson, the owner of the dog, was charged because police said he allowed the abuse and did nothing to come to the dog's aid.

Deputies later learned that Robinson is raising pit bulls and has at least one other dog.

Deputies said Robinson's father arrived at the scene and told deputies he had been asking "for weeks for them to get rid of those dogs."

The dog suffered numerous injuries and is recovering at Coral Springs Animal Hospital.
