Wet vs Dry Dog Food Comparison

With so many pet food options on the market, it can be overwhelming for owners to make the best choice for their dog. One of the most common questions every owner ask is which is best: wet or dry dog food, and we've got the answer.  

In this article, we explore the pros and cons of both wet and dry foods, covering essential nutrients, affordability, and more, so you can make the most informed decision about your dog's diet. 

What's the Difference Between Wet and Dry Dog Food?

There are multiple differences between wet and dry dog food, and which one’s better for your dog will depend on your dog. 

Wet and dry foods are processed differently, with dry foods typically made using a process called extrusion or baking the ingredients. Wet dog food, however, is typically made by adding all the ingredients and additives (like water, gravy, jelly, or thickening agents) into a can, tray, or pouch which is then sealed before cooking.  

These differences in processing are what set wet and dry dog food apart, with the key differences being:  

• Moisture content

• Shelf life

• Energy content

• Cost

• Convenience 

If you’re ever unsure about which type of food is best for your dog, speak with your vet. They can provide tailored advice and recommendations based on your dog’s age, lifestyle, or health.  

Is Dry Food Better for Dogs?

Many dog owners choose a dry dog food diet for their dogs. With its long shelf life and the convenience of a complete and balanced meal in one bag, it's easy to see why.  

Below, we outline the key pros and cons of dry dog food, and whether it's suitable for your dog.

Benefits of Dry Dog Food

• More convenient (easy to portion out and available to buy in supermarkets) 

• Long shelf life (even after opening) 

• Higher energy content (dogs can eat smaller amounts throughout the day) 

• More affordable than wet foods (of the same brand) 

• More versatile (Kibble can be used in puzzle and enrichment toys or as treats for training) 

• Easy to clean up (particularly when feeding messy puppies) 

Benefits of Dry Dog Food

• Harder to chew for some dogs (although senior dog foods tend to be made of softer kibble)

• Not as enticing (less aroma without added gravy or jelly) 

• More concentrated (might not fill your dog up) 

Should I Feed My Dog Dry Food?

Every dog is different, both in their preferences and their nutritional needs. Dry food may be the best pick for your dog if:  

•  Your dog prefers to eat little and often (dry food can be left out longer without spoiling) 

• Your dog is a messy eater (dry food is much easier to clean up) 

• You're feeding multiple dogs the same food (dry food works out cheaper and is easier to portion) 

• Your dog eats too fast (dry food encourages dogs to chew)

Is Dry Food Better For Dog's Teeth?

A common myth among pet owners is that dry dog food is better for your dog's dental health. However, veterinary professionals have debunked this and highlighted that regular brushing and professional cleanings are the best ways to maintain your dog's teeth.  

When your dog eats dry food, as with wet food, debris will undoubtedly remain on your dog’s teeth. As with humans, this debris can calcify and harden into tartar, which can cause damage and decay to teeth.

Is Wet Food Better for Dogs?

Some owners choose only to feed wet dog food diets, either because their dog prefers it, or because it's easier for them to chew. Just like dry food, there are pros and cons of wet food as well, which we explain below: 

Benefits of Wet Dog Food

• Longer Shelf Life (unopened wet food will keep until the expiry date)

• More appetising (the scent and texture can be more appealing to dogs)

• Higher water content (up to 78% moisture) helps your dog stay hydrated.  

• Easier to chew

• Keeps your dog fuller for longer (added moisture boost satiety)

Cons of Wet Dog Food

• Messier and harder to clean (when wet food drieds, it can crust to bowls, surfaces, and floors)

• Spoils quickly once opened (higher chance of contamination from bacteria)

• Must be refrigerated once opened (Wet food must be consumed within 2-3 days of being refrigerated)

• Not always available for veterinary dog food diets.  

Should I Feed My Dog Wet Dog Food?

While there are some dogs who benefit more from a dry diet, there are also those who could do better with a wet diet, such as:  

• Dogs who have trouble chewing (such as older dogs or those with dental problems)

• Dogs with low appetites (wet food has a more enticing aroma that can entice fussy eaters or dogs with impacted appetites)

• Dogs who don't drink enough (the higher moisture content helps keep your dog hydrated)

• Dogs who need support reaching a healthy body condition (wet foods can help dogs feel fuller for longer) 

How long can wet dog food sit out? 

Generally speaking, wet dog food that hasn't been consumed within 2 hours of opening should be thrown away. 

This timeframe drops to only 1 hour in the summer when warmth and humdity contributes to faster contamination. 

If refrigerated, wet dog food can keep for another 2-3 days (May vary by manufacturer. Always read the food storage guides)

Can You Mix Wet and Dry Dog Food? 

Yes! You can absolutely mix wet and dry dog foods to give your dog the best of both worlds!

 Just bear in mind your dog's daily caloric allowance, as mixing two complete foods can lead to overfeeding if not done properly.

You can learn more about how to mix feed dog food in our guide, or read on to discover the pros and cons of mixed feeding dogs:

Benefits of Mixing Wet and Dry Dog Food

• Can make kibble more appetising 

• Can encourage dogs to chew (especially puppies or dogs that eat too quickly)

• Adds moisture to your dog's diet to aid hydration

• Adds variety to your pet's meals

• Make your pet more adaptable to potential dietary changes

Cons of Mixing Wet and Dry Dog Food

• Risk of overfeeding (unless you're familiar with your dog's daily caloric allowance) 

• May take time to accept (a dog usually fed wet food may hesitate to eat kibble, and vice versa) 

• Not suitable for all dogs (some veterinary diets are only available in one formula) 

• Need to buy two separate foods (not all brands ofer their foods in wet and dry formulas)

What is the Best Food for My Dog?

What food is better for your dog ultimately boils down to one factor: your dog.  

While variety may seem like an excellent and balanced way to feed dogs‌, it’s the food’s nutritional content that matters. You need to ensure your dog gets all the nutrients, vitamins and minerals they need to stay fit and healthy, while also considering their life stage, lifestyle, and any health issues. For example, dogs with sensitive stomachs might not adjust well to dietary changes.
