Animal health
Good care, and the evidence behind it.
People will research their own health for weeks and then feed an animal whatever the bag suggests. From a house cat to a working herd, the animals in your care depend entirely on decisions made for them. This page sets out what is well established about their everyday wellbeing, where the research in animals is thinner than it is in people, and what belongs with a vet rather than with a website.
Written for anyone who cares a great deal about an animal and cannot tell which of the advice they are given actually holds up.
A study in people does not transfer to a dog, a horse or a cow. Most of what is sold for animals is borrowed from a human market, and the borrowing is where the evidence gets lost.

01 · The problem
Advice for animals is noisier than advice for people.
Almost everything sold into the human wellness market has since been copied across to animals. Supplements, special waters, devices, diets with a philosophy attached. It arrives with the same confident language and, in most cases, considerably less research behind it, because a study in people does not transfer to a dog, a horse or a cow.
Meanwhile the advice that circulates in breed groups and at the yard gate is passed on with real affection and no way to tell which parts hold up. The problem is not that owners do not care. It is that caring a great deal is not the same as being able to sort the claims.
Who is writing this
We have stood at the same gate.
We have been handed the same confident advice at the yard gate and in the breed group, delivered with real affection and no way to check it. So we went and looked at what has actually been studied in animals rather than borrowed from people.
We are not vets and we do not pretend to be. What we can do is separate what has been tested in the species you care about from what has been assumed, say how large and how long the studies were, and tell you plainly where the evidence stops. Where something is genuinely unresolved, we say so rather than picking a side.
How this works
Discover. Understand. Explore. Choose.
The same four steps on every page of this site, in that order. You are somewhere in the middle of them right now.
01
Discover
Find out the question is more interesting than you were told.
02
Understand
See what the evidence supports, and where it runs out.
03
Explore
Ask the person who sent you here to walk you through it.
04
Choose
Decide for yourself, with no pressure and no deadline.
02 · Why it matters
They cannot tell you, and they cannot choose.
An animal cannot say that something feels off, cannot decline a diet that does not suit it, and cannot ask for a second opinion. Every decision about its water, its food, its teeth, its movement and its surroundings is made by somebody else, usually with the best of intentions and imperfect information.
That puts more weight on plain observation than on any product. Animals are also good at masking discomfort, so slow changes get absorbed into the story of who that animal is. He has always been a fussy eater. She has slowed down because of her age. Sometimes that is true. Sometimes it is the first thing a vet would have wanted to hear about months earlier.
03 · What the evidence says
Three claims, three very different standards of proof.
Established
Water, body condition and teeth
Constant access to clean water, keeping an animal at a sensible body condition, and looking after its teeth are the least fashionable things on this page and the best supported. Dental disease is common in cats and dogs and frequently missed. Excess weight shortens working life and comfort in almost every species kept. None of this is contested.
Mixed
Diet composition and supplements
Nutrition in production animals has been studied in real depth. Nutrition in companion animals rather less so, and the supplement shelf less again. Research has explored joint supplements and omega-3 oils in dogs and horses with mixed and often modest findings, and product quality varies widely. Worth discussing with a vet rather than dismissing or assuming.
Often overstated
Anything carried straight over from people
Products marketed for animals on the strength of research done in humans. The species differ in ways that matter: cats and dogs metabolise many compounds differently, and several foods and medicines that are harmless to us are dangerous to them. A human result is a reason to ask the question in that species, never an answer already given.
This is an area of active research. Some of the studies referenced here are early, small, or conducted in laboratory or animal models rather than in people. We have said so wherever that is the case.
04 · The options
Three routes, in rough order of how much evidence sits behind them. The first two cost nothing beyond attention and are where almost all of the benefit lives. The third is where almost all of the money goes.
Knowing normal
How much this animal usually drinks, eats and moves, and what its coat, breath and gait are like on an ordinary day. Nothing else on this page works without it, because a change only means something if you know what it changed from.
What it will not do: replace an examination by a vet.
The everyday basics
Clean water always available and troughs and bowls actually kept clean. Feeding to condition rather than to habit. Teeth looked at. Movement suited to the animal. A settled environment with somewhere to get away from noise, heat and other animals.
What it will not do: treat an illness that has already started.
Anything added
Supplements, diet changes, water treatments and devices. The honest position is that these belong in a conversation with the vet who knows the animal, and that the question to ask is what has been shown in this species rather than what is claimed on the label.
What it will not do: work simply because it works in people.
05 · The limits
When to stop reading and call the vet.
This is not veterinary advice. Speak to your vet before changing the care of any animal. A page can tell you what is generally understood. It cannot see the animal in front of you, and that is the whole difference.
A marked change in drinking, eating, breathing, toileting or energy is a reason to phone a vet the same day rather than to search for an explanation. Never give an animal a human medicine or supplement without veterinary advice, because several are actively dangerous at doses that are unremarkable in people. If you keep livestock, medicine rules and withdrawal periods apply and no website can advise you on them.
Nothing on this page treats, prevents or cures any condition in any animal. A page about animal wellbeing that never says where its own subject stops is selling something.
What is at stake
An animal that cannot tell you what changed.
If you understand it
You can tell which advice is worth following, change one thing at a time so you can see what it did, and know when the answer is a vet rather than a product.
If you do not
Money spent on things borrowed from human marketing, changes you cannot evaluate, and a delay in getting a vet to look at something that needed looking at.
