Tyson, the miniature Lhasa-Chi (cross between a Lhasa Apso and a Chihuahua) is ten weeks old and believe to be the smallest dog in Britain. He is just four inches tall and weighs eleven ounces, making him just about the size of a grapefruit. Tyson was born on Mother’s Day in a litter of five puppies, all of which are much bigger than him. His owner, Rosemarie McLinden has had to build him a special crate as his brothers and sisters think that he is a toy to play with! Tyson is barely a quarter of the size of his siblings, but as you’ll see in the short video, he’s just a playful pup who wants to do what all dogs do – play and love.
