Pictured: The dalmatian who gave birth to a bumper litter of EIGHTEEN pups. She hasn't quite expanded her family to 101, but Button has still produced a pretty impressive number of little dalmatians. The three-year-old dog has given birth to a litter of 18, just a year after having 16 pups. Her litter is thought to be the largest born to a dalmatian in the UK. The average is about eight or nine.
