In one big bundle of joy, a Ballarat breeder is boasting the largest Dalmatian litter in Australian history and equalling a world record.

CC Dalmatians has kept quiet its 18-puppy litter for six weeks, to ensure they had a chance to thrive.

The puppies were hand-reared for four weeks, every four hours.

A social media post from Ballarat Veterinary Practice offered a unique insight into the litter's first check-up and vaccinations on Thursday night.

The post had achieved 2,700 likes and almost 300 shares by lunchtime on Friday.
