You read the labels. You check the ingredients. You avoid seed oils, limit sugar, and side-eye anything with a barcode longer than a haiku. You subscribe to Substacks that dissect institutional capture. You understand, probably better than most, that "the science" can be quietly purchased by the people it is supposed to regulate.

So let me ask you a question that might sting.

What did you feed your dog this morning?

If the answer is a brown pellet from a bag, you are running the same ultraprocessed food experiment on your dog that you have spent the last few years learning to reject for yourself and your family. And you are doing it for entirely understandable reasons, because the same machinery of institutional capture, industry-funded research, and reassuring pseudo-scientific language that once told you margarine was healthier than butter has been quietly operating in veterinary medicine for decades.

I am a practising veterinary surgeon in the UK. I have spent over 30 years in clinical practice, and I am the founding president of the Raw Feeding Veterinary Society. I also lecture on canine nutrition at the University of Glasgow and around the world. I was in Florida last year and San Diego the year before. I am writing a book on ultraprocessed food for dogs, because someone needs to say plainly what the pet food industry would rather you never thought about: your dog has been subjected to the most sustained ultraprocessed feeding experiment in mammalian history, and almost nobody noticed.

The Cleverest Marketing You Never Saw

Here is how it works, and it will feel familiar to anyone who has followed the corruption of nutritional science in human medicine.

The major pet food corporations do not merely sell food. They fund the university departments in the UK and the US where veterinary nutritional science is researched. They endow professorships. They provide free student packs and educational materials to veterinary schools. They sponsor the conferences where vets gather for continuing professional development. They supply the textbooks. They fund the bursaries. They stock the waiting room shelves and put posters on the surgery walls.

They do this so quietly and so comprehensively that most vets do not even realise they have been swimming in industry-sponsored water since the first day of vet school.

The result is predictable. Almost all large-scale nutrition studies published over the past 50 years have been conducted on extruded, grain-based diets produced by the very companies that funded the research. That research became what vets are taught.

Raw and fresh diets, by contrast, have received almost no industry funding, which means almost no large-scale trials. Vets are then honestly told there is "no evidence" for raw, because nobody with money has paid for that evidence to exist.

It is rather like sponsoring every study on buses and then declaring there is "no evidence" that bicycles work.

The World Small Animal Veterinary Association's Global Nutrition Committee now explicitly warns that most pet nutrition studies are industry-funded and says conflicts of interest should always be declared. RCVS Knowledge, the Royal College of Veterinary Surgeons in the UK, which runs the Evidence-Based Veterinary Medicine Network, notes that funding source is one of the strongest predictors of outcome in nutrition trials. JAVMA News has run pieces on corporate influence in veterinary education.

This is in the official documents. It is no longer fringe grumbling.

What Is Actually in the Bag

Commercial kibble is manufactured through a process called extrusion: ingredients are forced through a barrel at extreme temperatures and pressures, then puffed, dried, and coated with fats and flavour enhancers to make the result palatable. The process is industrial and efficient, producing a product with a shelf life measured in months or years.

It also does things to food that would...
