It turns out that the 9-month-old bull terrier has a taste for women's underwear. Workers found three pairs of women's underwear after they had passed through the dog's digestive system. As the underwear was fully intact, it appears Barney swallows it whole and does not enjoy chewing it. A veterinarian at the facility says that Barney is doing fine and will suffer no long-term effects.
Perhaps after a switch to a more regular diet, Barney will be able to break his strange habit. However, his new owners will be warned to keep him away from the laundry.
