Channel 5's eagerly anticipated 'The Truth About Your Dog's Food' is already causing controversy before it has even been screened. It's being broadcast at 9pm tonight (Thursday).

Guy Blaskey, Manging Director of the Pooch & Mutt company, which makes health supplements and healthy treats for dogs, has weighed into the argument, claiming there is no truth about pet food.

"Channel 5's PR machine seems to have gone in to overdrive with every man and their dog (excuse the pun) weighing in to the debate," said Guy (pictured left).

"Unfortunately, most of the people involved in the debate seem to either have a commercial agenda of their own, or be chosen for their looks more than their expertise.

"The truth about pet food is that there is no truth. There is no one-size fits all diet that will be right for every dog, just as there is no one-size fits all diet that will work for every human."

Guy believes the diet that is right for an owner's dog is the diet that they do best on and which is the best that he or she can afford.

"If your dog has bright eyes, a wet nose, a high quality coat, solid stools and you can feel their ribs with just a small covering of fat then what you are feeding them is right.

"It doesn’t matter whether it’s prime rib or polystyrene, if your dog is healthy that is what matters most – although obviously dogs would most likely not meet the healthy criteria on a polystyrene diet, and you certainly should not try it."
