Guy mostly u will find two kinds of markings in these dogs 1.Brand marking .villagers make these marking wid heated up IRON rods.They Usually crop the ears of the dogs at age of 6 months manually with sharp knifes with out sedation.They do give their brand marking at time of cropping of ears.They feel that this process of marking wid hot rods imporves dogs appetite during that harsh period of wounds result of cropping These are brand markings marking on their back legs are brand marking sort of thing 2.Scars made by boars.Hunting is the main part of their tradition once the season starts they hunt almost every day.They do hunt only wid dogs and spears. These are marking made by boars We cant find a single tiger in that region
