The science of dog appetite with Vet Dr Brendan Clarke

We've made the emotional case. We've made the behavioural case. Now it's time for the science. In the final episode of For Pet's Sake: The Joy of Real Food, Charlotte Hawkins sits down with Dr Brendan Clarke — Clinical Director at Towerwood Vets and Chief Veterinary Advisor at Bella+Duke — to answer the question this whole series has been building to: what is actually happening inside your dog's brain and body when they love their food? From the thousands of scent receptors that shape how dogs experience a meal, to the gut-brain axis linking digestion to mood, to what dogs naturally choose when given the freedom to pick — this is the biology behind "Real Food = Real Joy," explained in plain English. Plus: what your dog's digestion, skin, coat and energy levels might be telling you about their diet. And to prove the point, meet Clementine, who's given a genuine choice between two bowls — no explanation needed, the answer speaks for itself.
