Wet vs Dry Dog Food: What Should You Feed Your Dog?
There is no single correct answer to whether wet or dry dog food is better. Both are nutritionally complete options when they meet FEDIAF guidelines, and many dogs do well on either -or a combination of the two. The right choice depends on your dog's age, health, preferences, and your own lifestyle. When in doubt, your vet is always the best person to ask.
Key takeaways
- Both wet and dry dog food can provide complete and balanced nutrition when they meet established nutritional standards.
- Wet food has a higher moisture content, which can support hydration -particularly useful for dogs that don't drink much.
- Dry food is generally more cost-effective, easier to store, and may support dental health.
- Mixed feeding -offering both wet and dry -is a popular approach that combines benefits of each.
- Any significant change to your dog's diet should be made gradually, and your vet should be your first port of call if you have health concerns.
What Is the Difference Between Wet and Dry Dog Food?
The most obvious difference is water content. Wet food -whether it comes in tins, trays, or pouches -typically contains around 70–85% moisture. Dry food (also called kibble) usually contains no more than 10–12% moisture.
Beyond that, the two formats differ in texture, caloric density, palatability, and shelf life. Wet food tends to be softer and more aromatic, while dry food is harder and more energy-dense per gram. Both can be nutritionally complete, provided they are formulated to meet FEDIAF (European Pet Food Industry Federation) nutritional guidelines -look for this stated clearly on the packaging.
What Are the Benefits of Wet Dog Food?
Higher moisture content. Dogs often don't drink enough water on their own. Wet food contributes meaningfully to daily fluid intake, which matters for overall health and kidney function. According to UK Pet Food, moisture is an essential nutrient, and wet food can be a practical way to increase a dog's water consumption without them noticing.
High palatability. The texture and smell of wet food is appealing to most dogs. This makes it particularly useful for fussy eaters, older dogs with reduced appetite, or dogs recovering from illness. Always check with your vet before using food as an appetite stimulant for a dog that is unwell.
Softer texture. Dogs with dental problems, missing teeth, or difficulty chewing benefit from wet food's softer consistency. Puppies transitioning from their mother's milk, and senior dogs, often find wet food easier to eat.
Variety of textures. Wet food comes in chunks, pâté, jelly, and gravy formats, which can keep mealtimes interesting for dogs that become bored easily.
Potential drawbacks to consider:
- Shorter shelf life once opened (usually 24–48 hours refrigerated)
- More expensive per calorie than dry food
- Can contribute to plaque build-up on teeth if dental hygiene is not maintained
- Packaging requires more storage space and disposal consideration
What Are the Benefits of Dry Dog Food?
Convenience and shelf life - Dry food is easy to measure, store, and travel with. An unopened bag can last months, and leftovers in the bowl won't spoil quickly at room temperature.
Cost-effective - Because dry food is more energy-dense, you typically feed smaller quantities by weight, making it more economical than wet food for most dog sizes.
Dental health - Some dry kibbles are designed to reduce tartar build-up through their abrasive texture. However, it's worth noting that kibble alone is not a substitute for regular tooth brushing or veterinary dental checks. UK Pet Food highlights that dental hygiene should be treated as a routine part of your dog's care regardless of food type.
Easier portion control - Measuring dry food is straightforward, which helps with maintaining a healthy weight -particularly important for breeds prone to obesity.
Potential drawbacks to consider:
- Lower moisture content means your dog needs to drink more water to compensate
- Some dogs find dry food less appealing, particularly if they have been used to wet food
- Highly processed formulations vary significantly in quality -always check the ingredient list and nutritional declaration
Should I Feed My Dog Wet and Dry Food Together?
Mixed feeding -combining wet and dry food at the same meal or across different meals -is a widely used approach and works well for many dogs and owners.
It can allow you to offer the hydration benefits of wet food alongside the convenience and dental benefits of dry food, while also adding variety to your dog's diet. Many owners feed dry food as a main meal and use wet food as a topper, or alternate between the two at different mealtimes.
If you do mix wet and dry food, the most important thing is to get the total daily calorie intake right. Each product will have its own feeding guidelines based on your dog's weight -follow both and adjust accordingly so you are not overfeeding. Many manufacturers include combination feeding guidance on their packaging.
How Do I Switch My Dog From One Food Type to Another?
Any dietary change should be made gradually over 14 days to avoid digestive upset. A sudden switch -even to a higher-quality food -can cause loose stools or stomach discomfort.

Some dogs with sensitive stomachs may benefit from an even slower transition over two weeks. If your dog shows signs of prolonged digestive upset during a food change, speak to your vet.
Does It Matter What Life Stage My Dog Is At?
Yes, it does. Puppies, adults, and senior dogs have different nutritional requirements -not just different quantities, but different ratios of protein, fat, calcium, and other nutrients.
Always choose a food labelled for your dog's specific life stage, or one labelled as suitable for "all life stages." FEDIAF nutritional guidelines set the standards that manufacturers must meet for each category. A food labelled "complete" should meet all of your dog's nutritional needs without requiring supplementation.
- Puppies often benefit from wet food's softer texture and higher palatability as they adjust to solid food.
- Adult dogs can thrive on wet, dry, or mixed diets -individual preference and health will guide the choice.
- Senior dogs may find wet food easier to chew, and their hydration needs can make the moisture content beneficial.
If your dog has a specific health condition that affects their diet -kidney issues, weight management needs, food sensitivities -speak to your vet or a veterinary nutritionist before making changes.
How Much Should I Feed My Dog?
Feeding quantities depend on your dog's weight, age, activity level, and the specific food you are using. There is no universal figure.
Every complete dog food product is required to provide feeding guidelines on its packaging. Use these as your starting point, then adjust based on your dog's body condition. You should be able to feel -but not clearly see -your dog's ribs. If you are unsure whether your dog is at a healthy weight, your vet or vet nurse can do a body condition score assessment.
If you are mixing wet and dry food, you will need to calculate portions from both products to avoid overfeeding. Many brands provide a mixed feeding guide for exactly this purpose.
