"We found this stray dog after two days, and it just followed us for 2,000km. We named him U.B after Ulan Bator, our finish point. He is probably ten years old, and he has just walked the whole country. He looks like a black wolf and fends for himself by hunting rabbits. He’s not domesticated in any way but still shows affection and love like any other dog. And he’s a great guard dog - we could leave the cart which is loaded with all our gear outside in any town, and we know it will be fine because U.B ferociously defends it."
