When it comes to staying fit and trim, humans never suffer a shortage of potential approaches.

But what about your pet? Exercise and a healthy diet can be just as important to the furry members of your family, with the latter in particular continually presenting itself as an issue for dogs.

So what should you be feeding your dog?

At least one Toronto trainer, Peter Brown, swears by the raw food diet.

Essentially it's a balance of meat, vegetables and fruit that you yourself might eat, pureed so that it only looks like dog food.
