Sergeant’s Pet Care, the US company specialising in over-the-counter health care products for dogs and cats, is organising a naughty pet photo contest, at which pet owners will have the chance to win a high-end digital camera or Flip MinoHD. According to the company, the contest is not only designed to give pet owners a place to display the humorous side of their pets’ behaviour, but to provide them with a way of helping their pet overcome stress-induced behaviours as well.
