"Ten-week-old Tyson, who is a cross between a Lhasa Apso and a Chihuahua, is believed to be Britain's smallest dog.
The pup stands at just four inches (10cm) tall and weighs just 11 ounces (300g).
Owner Rosemarie McLinden has had to build a special crate for the miniature puppy to live in because his bigger brothers and sisters mistake him for a toy to play with.
Tyson was born on Mother's Day as part of a litter of five but is barely a quarter of the size of his siblings."
