Wet, Dry, Fresh or Raw Dog Food? A Practical UK Guide

Updated September 2026

Choosing what to feed your dog can become surprisingly complicated.

One person tells you kibble is perfectly adequate. Another says dogs should only eat fresh food. Somebody else insists raw is more natural, while another owner would never feed it.

The problem is that the food’s format does not, by itself, tell you whether it is a good diet.

For most healthy dogs, I would start with a much simpler question:

Is the food complete, appropriate for this dog, fed in the right amount and something the dog and household can manage consistently?

Wet, dry, commercially prepared fresh and commercially prepared raw foods can all be sold as complete diets.

That does not mean they are identical. They differ considerably in moisture, storage, convenience, cost, hygiene requirements and how practical they are for individual dogs and owners.

This guide will help you compare them without getting caught up in the idea that there must be one correct way to feed every dog.

For my wider feeding guidance, start with my Dog Food & Nutrition Guide.

Summary

• Dry, wet, commercially prepared fresh and commercial raw foods can all form part of an appropriate diet when they are nutritionally complete and suitable for the individual dog.
• Look for the word “complete” rather than relying on words such as natural, premium, fresh or high meat.
• Dry food is convenient, easy to weigh and useful for training and enrichment.
• Wet food contains considerably more moisture and can suit dogs who prefer softer food.
• Fresh cooked food may be convenient and appealing, but “fresh” does not automatically mean nutritionally superior.
• Raw food requires additional hygiene precautions because uncooked animal ingredients can carry pathogens that may affect dogs and people.
• Homemade cooked and homemade raw diets are much more difficult to balance properly than they may appear.
• Your dog’s age, health, body condition, activity, preferences and any veterinary requirements matter more than feeding trends.

First, check whether the food is complete

Before comparing wet with dry, or fresh with raw, check the label.

One of the most useful words you can find is “complete”.

Complete dog food is intended to provide the nutrients your dog needs when fed according to the instructions.

A complementary food is designed to be fed alongside other food. Treats, chews, mixers and many toppers are complementary rather than complete.

A food can look wholesome, contain expensive ingredients and arrive in attractive packaging while still being complementary.

Equally, a less glamorous-looking product may be nutritionally complete.

That is why I would check the label before getting too caught up in the marketing on the front of the packet.

You should also check that the food is intended for dogs and is appropriate for your dog’s life stage.

Puppies have different nutritional requirements from adult dogs. Older dogs and dogs with medical conditions may also have specific needs.

My Dog Food & Nutrition Guide explains complete and complementary feeding in more detail.

Wet, dry, fresh and raw at a glance

Food type	Useful features	Things to consider
Dry food	Convenient, easy to store and weigh, useful for training and food enrichment	Low moisture content, portion sizes still need measuring, ordinary kibble should not be assumed to clean teeth
Wet food	High moisture content, soft texture, often appealing to dogs	Larger feeding volumes, opened food requires refrigeration, can be less convenient for training
Commercial fresh cooked food	Often highly palatable, portioned products can be convenient	Usually needs fridge or freezer space, may cost more, “fresh” does not prove nutritional superiority
Commercial raw food	Can be sold as a complete diet, usually high in moisture	Requires careful storage, defrosting and hygiene, uncooked animal ingredients can carry harmful bacteria
Homemade food	Gives the owner control over ingredients	Much harder to make nutritionally complete, whether cooked or raw, and should be properly formulated with professional guidance

The right answer does not have to be one column.

Some dogs eat one food format throughout their lives. Others have a combination.

What matters is that the total diet remains appropriate.

Dry dog food

Dry dog food usually means kibble, although there are other dried formats available.

It is popular for good practical reasons.

It stores easily, portions can be weighed accurately and you can use some of the dog’s normal daily food for training, scatter feeding or suitable food toys.

That can be particularly useful if your dog receives frequent food rewards.

Rather than continually adding extra treats, some of the normal meal can become part of a walk, training session or enrichment activity.

Dry food contains much less moisture than wet food, so a dog eating dry food will normally obtain more of their water separately.

Fresh drinking water should always be available.

Does kibble clean a dog’s teeth?

I would be cautious about assuming that ordinary dry food cleans a dog’s teeth simply because it is crunchy.

Some specially designed dental diets may help with plaque or tartar, but that does not mean every dry food provides the same benefit.

Consider dental care separately from choosing between wet and dry food.

If your dog has bad breath, painful gums, difficulty chewing, starts dropping food, or suddenly refuses something hard they previously ate happily, speak to your veterinary practice.

Wet dog food

Wet food usually comes in tins, trays or pouches.

Its main difference from dry food is obvious as soon as you open it. It contains considerably more water.

That can make it appealing to some dogs and means part of their daily water intake is coming from their food.

It can also be easier for dogs who prefer a softer texture.

The feeding quantity may look much larger than the equivalent amount of dry food because much of the weight is water.

That doesn’t mean wet food is less nutritious.

It simply means you can’t always compare wet and dry foods by weight or the percentages on the packet.

Once you open wet food, follow the manufacturer’s storage instructions and refrigerate it as required.

Do not leave wet food sitting around for long periods, particularly during warm weather.

Be careful when comparing protein percentages

This catches people out.

You might see a wet food containing 9 per cent protein beside a dry food labelled as 25 per cent protein and assume the dry food contains far more protein.

It is not that simple.

Wet food contains much more water.

To make a meaningful nutritional comparison between foods with very different moisture levels, you need to compare nutrients on what is known as a dry matter basis.

For most owners, you do not need to start doing calculations every time you buy dog food.

The key is not to judge two different food formats by a single percentage printed on the front or back of the packet.

What is fresh dog food?

“Fresh” has become a very popular description.

Commercial fresh dog food is usually made from ingredients that have been cooked and then supplied chilled or frozen.

Some companies deliver individual portions directly to the owner’s home.

That can be very convenient.

Some dogs also find these diets extremely appealing.

However, I would not assume that fresh automatically means better.

Freshness, appearance and ingredient descriptions do not replace nutritional balance.

Check whether the product is labelled as complete, which dogs and life stages it is intended for, how much should be fed, and how it needs to be stored.

A fresh product that is complementary should not quietly become your dog’s main diet simply because it looks more like food you might prepare yourself.

Is fresh food better than kibble?

Not automatically.

There is a tendency to compare dog food with human convenience food and assume that something described as fresh must therefore be healthier than something dried.

Dog nutrition is more complicated than that.

The important question is whether the finished diet provides the dog’s required nutrients in appropriate amounts.

A properly formulated complete dry food can provide appropriate nutrition.

So can a properly formulated complete fresh food.

I would base my decision on your individual dog rather than the appearance of the food.

What about raw dog food?

Raw feeding tends to generate stronger opinions than almost any other area of dog nutrition.

Some owners are extremely positive about it.

Others are strongly opposed.

My approach is not to tell somebody that feeding raw automatically makes them a good or bad owner.

It is to be clear about the additional considerations.

Commercial raw dog food can be sold as either complete or complementary, so once again the label matters.

Raw diets also require particularly careful handling because the animal ingredients have not undergone cooking that would otherwise destroy many harmful organisms.

Raw meat can contain bacteria and other pathogens. These can potentially affect the dog, the person preparing the food and other people in the household.

Good kitchen hygiene therefore becomes particularly important.

Raw food should be stored, defrosted and handled according to the manufacturer’s instructions. Hands, bowls, utensils and food-preparation surfaces need thorough cleaning after contact.

The British Small Animal Veterinary Association recommends strict hygiene measures where raw-meat-based diets are fed.

Households containing people who may be particularly vulnerable to infection need to consider this risk especially carefully.

Is raw food healthier?

I would be wary of anyone presenting that as a settled fact.

Owners sometimes report improvements after changing to raw food, including differences in coat, stools or enthusiasm for meals.

Individual experiences matter to individual owners, but they do not demonstrate that raw feeding is healthier for dogs generally.

The World Small Animal Veterinary Association states that there is currently no evidence that raw meat-based diets provide health benefits over commercial diets or balanced home-cooked diets.

That does not mean every dog eating commercial raw food will become ill.

It means the claimed advantages need to be considered alongside the recognised hygiene and nutritional risks.

What about raw bones?

I would not recommend adding bones simply because a diet is described as natural.

Bones can cause fractured teeth, choking, digestive obstruction and internal injury.

This includes risks associated with both cooked and uncooked bones.

There are safer ways to provide chewing opportunities and enrichment.

Commercial raw and homemade raw are not the same thing

This distinction matters.

A commercially produced raw food can be formulated as a complete diet and manufactured under controlled conditions.

A homemade mixture of meat, offal, vegetables and bone is not automatically nutritionally balanced.

Dogs require nutrients in particular amounts and proportions.

Getting one ingredient approximately right does not compensate for getting another badly wrong.

This becomes particularly important with growing puppies.

If you want to feed a homemade diet as your dog’s main food, I would discuss the formulation with your veterinary team or an appropriately qualified veterinary nutrition professional rather than relying on a recipe from social media.

What about homemade cooked food?

Cooking the ingredients removes some of the microbiological concerns associated with raw meat, but it does not solve the nutritional balancing problem.

Chicken, rice and vegetables may look like a healthy meal.

That does not mean they provide every nutrient your dog needs in the right proportions when fed day after day.

My older Homemade Dog Food Guide covers this separately, but professional nutritional guidance matters here.

A homemade diet should be formulated as a diet, rather than assembled from a collection of ingredients that happen to be safe for dogs.

Can I mix wet and dry dog food?

Yes, many owners do.

There is no general rule requiring a healthy dog to eat only one format.

The important issue is the total amount.

If the packet says your dog requires a full daily allowance of dry food, adding a full allowance of wet food on top obviously doubles the intended intake.

If you mix complete foods, adjust the quantities so the combined amount remains appropriate.

The manufacturer’s mixed-feeding guidance can help.

Monitor your dog’s body condition and weight rather than assuming the packet quantity will be perfect for every individual.

Can I mix fresh food with kibble?

Potentially, yes.

There is no general nutritional rule that says cooked fresh food and kibble cannot appear in the same diet.

The more important question is what is being added.

If both products are complete foods, the portions need adjusting.

If the fresh element is a topper or complementary food, be careful that extras do not gradually displace too much of the balanced main diet.

This is the same principle I use with training treats.

Something being healthy in isolation does not mean unlimited quantities improve the overall diet.

Which food is best for a fussy dog?

Changing foods repeatedly is not always the answer.

A dog may genuinely prefer one texture or flavour, but reduced appetite can also be associated with dental discomfort, digestive problems, stress, medication or illness.

If your dog suddenly becomes reluctant to eat a food they previously enjoyed, particularly alongside other changes, speak to your vet rather than continually offering more exciting alternatives.

If your dog is otherwise well and has always been selective, factors such as texture, smell, feeding environment and routine may influence what they accept.

What about dogs with allergies or sensitive stomachs?

Do not choose a diet purely because the packet says “sensitive”, “grain-free”, “hypoallergenic” or “natural”.

Those words do not diagnose the reason your dog is having problems.

Persistent itching, recurrent ear problems, vomiting, diarrhoea or other digestive changes deserve proper veterinary assessment.

A veterinary elimination diet needs to be controlled carefully.

Randomly moving between several proteins, treats, chews and toppers can actually make identifying a problem more difficult.

Dogs with pancreatitis, kidney disease, diabetes, gastrointestinal disease or another diagnosed condition may also need feeding advice specific to that condition.

How I approach feeding when I care for somebody else’s dog

When I am dog walking, visiting or house sitting, my job is not to redesign somebody’s dog’s diet.

I follow the feeding routine agreed with the owner.

That includes the correct food, amount, timing, storage instructions, treats and any important restrictions.

Routine can be particularly useful when an owner is away.

A house sit is not the time for me to introduce a fashionable new food because somebody on the internet says it is better.

If I notice something unusual, such as a significant change in appetite, vomiting, diarrhoea or difficulty eating, I let the owner know and follow the agreed veterinary and emergency arrangements.

That same principle applies when choosing food for your own dog.

Consistency and observation are often more useful than continually chasing the next feeding trend.

How I would choose between wet, dry, fresh and raw

I would ask the same questions regardless of the packaging.

Is the main food complete?

Is it appropriate for the dog’s age and life stage?

Does your dog remain at a healthy body condition on it?

Does their digestion appear normal?

Can you store and prepare it safely?

Can you afford to feed it consistently?

Does it work with any health or veterinary requirements?

Does it suit your dog’s preferences without creating an unnecessarily complicated routine?

If raw food is involved, can everybody in the household manage the additional hygiene requirements safely?

Those questions tell you far more than whether somebody online thinks one feeding method is superior.

When I would speak to a vet before changing food

For a healthy adult dog, owners will often be able to choose between suitable complete commercial foods themselves.

I would involve your veterinary team sooner if your dog is a growing puppy, pregnant, significantly underweight or overweight, has a diagnosed medical condition, is taking medication, has persistent digestive problems, has suspected food allergies, is losing weight unexpectedly or has suddenly changed their eating habits.

I would also seek advice before moving to a homemade diet.

Frequently asked questions

Is wet food healthier than dry dog food?

Not automatically.

Both can provide appropriate nutrition when they are complete and suitable for the individual dog.

They differ mainly in factors such as moisture, storage, portion size, texture and convenience.

Is dry dog food bad for dogs?

A properly formulated complete dry dog food can provide appropriate nutrition for a healthy dog.

The fact that it is dry or processed does not, by itself, mean it is unsuitable.

Is fresh dog food healthier than kibble?

“Fresh” describes the food format or marketing position rather than proving superior nutrition.

Check whether the food is complete and suitable for your individual dog.

Is raw dog food better for dogs?

There is not good evidence that raw feeding provides general health benefits over appropriately balanced commercial or cooked diets.

Raw feeding also introduces additional microbiological risks and therefore requires careful hygiene.

Can dogs eat wet and dry food together?

Yes.

Adjust the amounts so you are not feeding the full daily quantity of both diets.

Can I use dry food for dog training?

Yes.

If your dog values their normal food, setting aside some of the day’s measured allowance for training or enrichment is an easy way to avoid adding unnecessary calories.

Does my dog need variety?

Dogs do not require a constant rotation of foods simply to make their diet interesting.

Some dogs tolerate changes easily. Others develop digestive upset.

Variety can also come from walking, sniffing, enrichment, play and reward-based training rather than continually changing the contents of the bowl.

Which dog food would you personally recommend?

I would not recommend one brand or food format for every dog.

I would look for a complete diet appropriate for the individual dog’s life stage, health and needs, then consider how well the dog does on it and whether the feeding system is practical for the household.

Final thoughts

There does not need to be a winner between wet, dry, fresh and raw dog food.

Each format has advantages and drawbacks.

A beautifully packaged fresh food is not automatically better than kibble.

Kibble is not automatically better because it is convenient.

Wet food is not nutritionally weak simply because much of its weight is water.

And raw food should not be presented as either a miracle diet or something every dog owner must be frightened of.

Start with nutritional completeness.

Consider your individual dog.

Look at their health and body condition.

Think about safe storage, preparation, cost and the reality of feeding the diet every day.

Then choose the option that works for the dog in front of you, not the feeding trend making the most noise online.

This guide provides general information about feeding healthy dogs and does not replace individual veterinary or veterinary nutrition advice. Speak to your veterinary practice before making significant dietary changes if your dog is growing, pregnant, unwell, underweight, overweight, taking medication or has a diagnosed or suspected medical condition.
