This is the hilarious moment a bossy pet tortoise chases away two bulldogs. <br /><br />Three-year-old Mama was wandering around the garden with the when the two puppies were let loose on Monday afternoon. <br /><br />The curious 'exotic bullies' breed of dog - three-month-old Joker and five-month-old Coke - walked cautiously towards Mama to try to play.<br /><br />But the surly tortoise turned the tables and became the 'bully' herself by chasing away the dogs from her territory. <br /><br />She even headbutted and kicked out at the two bulldogs which were left shaking in fright - far different from their fearsome reputation.<br /><br />The two dogs were then both too scared to go near the bossy reptile at owner Weeraphat Ken's garden in Chiang Mai, northern Thailand.<br /><br />Weeraphat, 31, said: ''Mama is the boss, even with dogs. I think she wanted to show them that she was in charge. She was quite aggressive, that's why we call her Mama.<br /><br />''Most people think that bulldog breeds are aggressive but these two are just puppies and they were scared of a tortoise. <br /><br />''I'm hoping that they will get used to to being around each other and can play together soon.''
