Four out of ten UK dogs will over-indulge this Christmas, according to a survey from Wholesome Nutrition Ltd, manufacturer of Britain's first weight-loss dog food, Formula K (http://www.formulak.co.uk/). As a result, a staggering 29% of the nation’s dogs will be on a diet by the New Year.

Over one in four canines will munch mince pies this Christmas, while 17% will wolf down Brussels sprouts. The survey also suggests that 62% of dogs prefer sausages and 75% tuck into turkey. One in five dogs is partial to Christmas pudding and the same number love Christmas cake.

As a result of all this food, 43% of hounds will over-eat at Christmas, which is almost as bad as their owners - 57% of whom will over-indulge. At the end of the feasting festival, one-third of owners will go on a diet, where they will be joined by 29% of the country’s dogs.

Kit Sadgrove, founder of Formula K, says: “People are treating their dogs as part of the family. As far as Christmas over-indulgence is concerned, this survey shows you can hardly tell man and his best friend apart!"

Dogs love garlic bread, chips with gravy and Yorkshire puddings. Their favourite Christmas foods include cat biscuits, roast potatoes, ice cream and Chewits.

There are no real differences among the regions. Scots and Welsh indulge their dogs just as much as people in the South. However, the message that chocolate is dangerous to dogs is getting through: only one person in a hundred says they would give it to their dog.

When it comes to Christmas Eve, three quarters of all dogs will receive a small Christmas stocking, and a whopping 88% will have Christmas presents. A mere 6% of owners sternly say they won’t let their dogs have human treats.
