The intense encounter forced the homeowner to get a shot, pay more than $200 in medical bills and left him wondering who the stranger is caught on his Ring camera.Ulibarri was stepping outside his Tampa Heights home to take his small dogs out for a walk when a pit bull came running into his yard and headed straight for his dog named Gizmo. Ulibarri tried to separate the dogs and after a couple of seconds the pit bull's owner came running to the porch. He picked up his dog by the collar and dragged him away.Ulibarri's mother asked the stranger, "Do you not have your dog on a leash?" and he responded "No, he was on a leash but I let him go because it was choking him."Gizmo was left with a gash under his eye and bite marks. The dog is on antibiotics. Ulibarri had a nick on his finger. He asked the stranger whether the dog had its rabies shot but the man responded that he didn't know. Ulibarri was forced to get a tetanus shot. Altogether, the encounter cost Ulibarri more than $200 of out pocket in medical bills.Ulibarri requested information from the man who gave him an address and a phone number but not his name. Ulibarri reported the situation to animal control,who Ulibarri says, told him all the information was fake. Ulibarri is especially concerned this could happen again to another family with pets or young children.Ulibarri is asking people to take a close look at the video and see if they recognize the pit bull's owner. Also, he reminds pet owners to always leash up their animals.
