Should your dog eat dry kibble, wet food, or a combination of both?
There is no universal winner.
Dry and wet dog foods can both provide complete and balanced nutrition. The better choice depends on your dog’s life stage, size, eating habits, hydration needs, dental health, calorie requirements and your budget.
The key is to compare the foods based on what they actually provide, not simply whether one looks more natural or appetising.
Dry vs. Wet Dog Food at a Glance
These are general differences. Individual products can vary considerably.
1. Moisture: The Biggest Difference
The most obvious difference is water.
Dry kibble contains relatively little moisture, while canned and other wet foods contain substantially more. This means a dog eating wet food receives a significant amount of water directly from its meals.
This can be useful for dogs that don’t drink much.
It can also be useful when a veterinarian wants a dog to increase its overall water intake.
Wet food is less calorie-dense by weight.
A dog can therefore eat a much larger physical portion of wet food while consuming a similar number of calories to a smaller portion of kibble.
That can be useful for dogs that enjoy eating large meals.
2. Cost Per Calorie Matters More Than Cost Per Bag
Comparing dog food prices by the size of the bag or box can be misleading.
A 12 kg bag of kibble contains far less water than the same weight of wet food, meaning you need to compare calories, not simply kilograms.
The calculation is straightforward:
Cost per 1,000 calories = price ÷ total calories × 1,000
For example:
Dry food: $50 for 20,000 kcal
Wet food: $50 for 10,000 kcal
The two products cost the same, but the dry food costs $2.50 per 1,000 kcal, compared with $5 per 1,000 kcal for the wet food.
In practice, wet food is generally more expensive per calorie because you are also paying to package and transport a large amount of water.
So when comparing foods, check the kcal/kg or kcal/can information rather than judging value from the package price alone.
3. What About Dental Health?
This is where one common dog-food myth needs correcting.
You may have heard:
“Dry food cleans your dog’s teeth.”
It is not that simple.
Standard kibble does not automatically provide meaningful dental cleaning. WSAVA’s dental guidelines note that ordinary dry food can crumble when dogs bite it, providing little cleaning at the gum line where periodontal disease begins.
However, some specifically designed dental diets use larger, differently textured kibble to increase tooth contact and help reduce plaque and tartar.
Look for products recognised by the Veterinary Oral Health Council (VOHC) when dental benefits are a priority.
So the better rule is:
Dry food ≠ automatically good for teeth.
A properly designed dental diet can provide dental benefits.
And regardless of food type, brushing and veterinary dental care remain important.
4. Which Is Better for Puppies?
For puppies, the most important question isn’t dry versus wet.
It is:
Is the food complete and appropriate for growth?
Puppies have different nutritional requirements from adult dogs, so choose a food formulated for the appropriate growth stage.
Small and toy-breed puppies
Small dogs have relatively high energy requirements per unit of body weight.Dry food can therefore be convenient because a small volume can provide a substantial number of calories.
Large-breed puppies
Large-breed puppies need particularly careful nutritional management because excessive energy intake and inappropriate nutrient levels can contribute to abnormal skeletal development.
Choose a diet specifically designed for large-breed puppy growth where appropriate, and follow feeding guidance rather than simply feeding until the puppy appears full.
Picky puppies
Wet food can be useful when palatability is an issue. Its stronger smell, softer texture and variety of formats can make it more appealing to some dogs.
A combination of wet and dry food can also work perfectly well, provided the overall diet remains nutritionally appropriate.
5. What About Adult Dogs?
For a healthy adult dog, either format can work.
Dry food may suit:
Dogs that prefer to graze
Owners who want easy portion control
Dogs using automatic feeders
Owners looking to minimise feeding costs
Dogs that benefit from a specifically formulated dental diet
Kibble is convenient, easy to measure and has a long shelf life.
Wet food may suit:
Picky eaters
Dogs that need increased water intake
Dogs that prefer soft textures
Dogs where a larger meal volume is useful
Wet food can also make medication easier to administer for some dogs.
6. Does Breed Change the Decision?
Breed itself doesn’t automatically determine whether a dog should eat wet or dry food.
But breed-related characteristics can influence what works best.
Toy and small breeds
Small kibble can be easier for tiny mouths to pick up and chew. Small dogs also have relatively high energy needs per kilogram, making calorie density important.
Large and giant breeds
For large dogs, calorie control and appropriate growth or maintenance nutrition are more important than whether the food comes in a can or a bag.
Short-muzzled breeds
Dogs with crowded or rotated teeth can have increased periodontal disease risk. VCA identifies toy breeds, small dogs and short-muzzled breeds as particularly prone to dental problems.
For these dogs, don’t assume ordinary kibble is enough. Discuss an appropriate dental strategy with your veterinarian.
7. What About Senior Dogs?
Senior dogs don’t automatically need wet food.
Instead, look at their individual needs.
A senior dog that has difficulty chewing may find wet food easier to eat. A dog that needs to control calorie intake may benefit from a lower-energy-density food that allows a larger meal volume.
The important thing is to match the nutrient profile and calorie density to the individual dog.
8. Can You Mix Wet and Dry Food?
Yes.
There is nothing inherently wrong with feeding both.
A mixed approach can provide:
the convenience of kibble;
additional moisture from wet food;
greater variety;
improved palatability for some dogs.
The important point is to account for the calories from both foods.
If you add wet food on top of the normal amount of kibble without adjusting portions, your dog’s total calorie intake can increase.
So, Which Should You Choose?
There is no universal “best” format.
Choose dry food when convenience, calorie density, portion control and cost are priorities.
Choose wet food when hydration, palatability, soft texture or larger meal volume are more important.
Choose both when a combination works better for your dog.
And if dental health is your concern, don’t simply assume that any dry food will clean your dog’s teeth. Look for evidence-backed dental products and maintain proper dental care.
Most importantly, start with the nutritional adequacy statement and your dog’s individual needs.
The best dog food isn’t the one with the most impressive packaging. It’s the one that provides appropriate nutrition in a format your dog can eat, digest and thrive on.
