Dogs enjoy fewer walks in the winter - because their owners don't like going out in the cold, a study has revealed. More than half (56 per cent) of owners admit their dogs get less exercise when the temperature drops due to their reluctance to venture outside. Alarmingly, one in six admitted they pray for grim weather so they have an excuse to avoid taking their dog for a stroll. As a result, dog owners reckon their pooch gets an hour less exercise every week compared to the summer. Sean McCormack, head vet at dog nutrition company Tails.com, which commissioned the study, said: "Any dog which is living by a nutritious and healthy diet is going to remain as enthusiastic as ever about their daily walks, even as the temperature plummets and the heavens open.
