Premium pet food has become big business.

Accompanied by her faithful canine co-host Gertie - a five-year-old rescue dog who is totally Zen until the postman calls - Sheila Dillon asks whether this is this new dog food focus is in our pet's best interest - or whether we're simply imposing our own food values on our canine companions?

Sheila visits Butternut Box - a food box delivery service creating nutritionally balanced meals delivered to the door, for dogs; hears from Glossop butcher John Mettrick who's launched a side-line making raw pet food; learns what goes into a high-end brunch for pampered pooches, at M Restaurant in London; and meets Agnes, a vegan dog-owner who's dog has also been vegan for nearly a decade.
