The Banavaram police registered a case.“There were multiple bites, particularly on the upper body,” said sub-inspector of police Munusamy. Police said both dogs might have attacked him.Rottweiler is a ferocious animal. It has powerful jaws and sharp teeth, said Dr T Manoharan, specialist –cum -deputy director (incharge) of Department of the Animal Husbandry, Vellore.“They will go wild when someone stops or disturbs them when they eat food. They get irritated and start attacking. They should be trained properly to obey the commands of the owner. Otherwise, they will pose a serious threat,” he said.Livestock sellers in Rottweil village in Germany created the particular breed to suit their demand, he said. “The butchers and livestock sellers will keep the money, which they made after selling the livestock in markets, in a leather belt tied around the dog’s neck. They did this to prevent thieves from robbing them.”
