Documentary following Karen Chamberlain, owner of the Barking Mad pet talent agency, which supplies everything from cute pooches to cuddly cats for films, TV and ad campaigns. Whether the casting call is for dogs, sheep, ponies, zonkeys or alpacas - no job is too big, too small or too ambitious for Karen. But after a troubling dry spell at the agency, Karen and husband Pete's dwindling savings account is keeping the company afloat, so it's make-or-break time for the couple. Will a Guinness World Record attempt for Lorraine Kelly, and a high-profile job for a potential new London mayor, help improve the agency's fortunes?
