This adorable dog loves the sound of his own name - and cracks a huge smile whenever he hears it. Two-year-old Aspin dog Liit runs over whenever his owners or neighbours call him. He arrives and always show his pearly whites in a large, toothy grin. Jhay-r Vega, from Pangasinan, the Philippines, said: ''Liit is my girlfriend's pet. Whenever I come to their house, he always welcomes me. He is such a cute dog.''
