A woman reckons she’s got Britain’s smallest PUG, a tiny little ball of snuffles that is smaller – than a drink CAN. Pip the tiny pug stands just less than four inches tall, and is half the size of her sister. The four-month-old runt of the litter is a purebred pug, who just never seemed to grow, according to owner Joanne Astley. Joanne, 54, decided to start breeding pugs last year, and was delighted when two-year-old Ruby gave birth to a litter of four in January. But her delight soon turned to shock when she realised that one of the puppies was half the size of the others.
