It took five liters of oil to remove most of the tar from his body, but with each careful effort, the dog, named Petro (after "petroleum"), showed signs of relief.

Despite the trauma he had endured, Petro remained calm and patient throughout the ordeal. Once most of the tar was removed, he was taken to a veterinary clinic for further evaluation.

Dr. Gretel expressed concerns about the tar Petro had ingested, which could pose significant health risks. However, Petro's ability to eat and drink normally was an encouraging sign.
