BOSTON -- A Stoughton family's puppy was mauled to death last week at a doggy day care after it was left with dogs twice its size.

Margaret Milne told the Boston Herald she brought her 1-year-old Shih Tzu, Harley, to Tails-In-Motion, on Friday. The 20-pound dog was attacked by a golden retriever, two greyhounds and the day care owners' mixed-breed dog.

Harley was taken to Lloyd Animal Medical Center, suffering from multiple puncture wounds, but it later died.

Milne told the Herald that she doesn't want the dogs involved in the attack punished, but that the center was negligent because her dog was left alone with the larger animals.
