The veterinarians at Battersea Dogs and Cats Home said Barney, a 9-month-old Staffordshire bull terrier, was in his second day at the rescue when a volunteer spotted a pair of women's panties in his droppings, the Mirror reported Thursday.
The rescue said Barney passed two more pairs of panties during the following days.
"We thought we'd seen it all at Battersea, but clearly not. Who knows how Barney came to swallow so many pairs of pants. It will remain his secret but this little puppy is clearly a bit of a scavenger and we'll be advising his new owners to keep him well away from the laundry basket and the washing line," said Sam Barley, a veterinary surgeon at Battersea.
