Luckily for large breeds, they have more prominent jaws and teeth that make it easy to chew food and brush.

But, these gentle giants also tend to swallow their kibble whole instead of chewing it, thus missing out on the cleaning power. This is why it’s essential to buy a large breed dog food with the right kibble size.

How to Choose the Best Dog Food for Bad Breath

To help prevent bad breath or get rid of it, you need to know what’s causing it in your dog. Then, you’ll need to make the necessary changes in their diet and lifestyle. Here’s what you need to know. 

What causes bad breath in dogs?

What are the leading causes of bad breath in dogs? Here are some common reasons. 

Poor Oral Hygiene

Did you know that you’re supposed to brush your dog’s teeth? This helps remove tartar and plaque buildup, which can cause tooth decay and bad breath if not taken care of.

While a toothbrush and toothpaste are the best options, items like dental chews can work well too. 

Bad oral hygiene can cause other dental problems like oral infections, gum disease, and even organ damage. So to avoid bad breath and other issues, be sure to take care of your dog’s teeth as preventative maintenance. 

Periodontal Diseases

If your dog has poor dental health, periodontal disease can happen. It happens when periodontitis bacteria infects your dog’s mouth.

Usually, it has no signs or symptoms until it’s in an advanced stage. Once this happens, it can cause chronic pain, loss of teeth (or fractures), and gum erosion. 

This is why it’s important to brush away bacteria and food particles during regular tooth brushing.

This can remove the tartar and plaque that causes inflammation and irritation to the teeth and gums. And, it keeps dental disease away. 

Kidney & Liver Disease

Dental problems can cause other issues with your dog, including kidney and liver disease. This happens when the bacteria enter your pet’s bloodstream. This causes elevated liver and kidney enzymes, causing the organs to work overtime and wear out. 

It’s important to note that kidney and liver damage can cause death if left untreated. And, once the damage happens, you can’t reverse it.

If you suspect that your dog has periodontal disease, immediately take them to a vet to avoid more complications. 


Diabetes and gum disease usually go hand in hand in dogs. They feed off each other. Inflammation and infection from periodontal disease cause an unhealthy spike in blood-sugar metabolism.

This inflammation also decreases the body’s sensitivity to insulin.

You’ll need to treat the dental problems to get their diabetes under control. You’ll need to take your dog to the vet to get the best treatment plan, including teeth pulling or professional cleaning. 

Eating Habits

Dogs can, and will, eat everything they come in contact with — and fast. This can cause issues like bloat or cause dental problems with items pesticides or other toxic and problematic objects. And, it’s even worse if your dog likes to eat poop, eat rotten leftovers, or drink urine. 

To avoid possible tooth decay or breakage, try to avoid places where your dog can get into trouble (like leaving them off a leash in a park). And be sure that they chew their food slowly.

Breeds Prone to Bad Breath

Like other disorders and diseases, some dog breeds are prone to bad breath and periodontal disease. These include toy dogs, mini, and smaller dogs, plus dog breeds with narrow muzzles. 

For smaller dogs, jaws can sometimes be too small, causing compact teeth, sensitive jaws, and hard-to-reach crevices. So cleaning their teeth, yearly vet visits, and removing problematic teeth will be crucial.

Dogs with long snouts like Greyhounds, Beagles, and Saluki also deal with bad breath. Their jaws are about the same size as small dogs; thus, their teeth can be too close together. 

No matter what, it’s vital to ensure your dog’s dental health is in good shape. Keeping their teeth clean, brushing them, and regular vet visits can make a huge difference.

Can diet help eliminate bad breath?

Yes, it can. Certain ingredients can build strong bones and teeth, and kibble size (and shape) can help scrape off plaque and tartar. But it’s also important to note that diet can’t do everything alone.

It’s still important to clean your dog’s teeth with a toothbrush, or at the very least, give them chews and bones to help clean them. And if needed, look into a veterinarian prescribed diet.

What to Look for When Buying Food for Bad Breath

So what do you need to include in your dog’s food to help them have good oral health? Here are the ingredients to look for. 

Ingredients That Help Digestion

Prebiotics and probiotics make it easier for your dog to digest their food. And they can help keep gassiness, burps, and bad breath away and reduce inflammation in their joints.

While many dog foods already include probiotics, you can also use probiotic capsules if your vet approves the brand. 

Ingredients That Promote Dental Health 

When it comes to your dog’s dental health, other ingredients can promote shiny, strong, and healthy teeth. 

First, essential fatty acids like omega-3 are rich in DHA and EPA, which can help maintain gum health and prevent tooth decay. Of course, calcium is an essential nutrient for strong teeth. It strengthens the hard outer shell of your dog’s tooth, also called enamel. This helps prevent erosion and decay. 

Glucosamine and chondroitin are other ways to support dental health. These protein-building blocks help build and repair cartilage and gums. This helps protect your dog’s teeth and keep them from rubbing together. 

Last but not least, antioxidants do more than boost your dog’s immune system. They also reduce the accumulation of tartar buildup and plaque. This can help prevent periodontal disease in many dogs.

Kibble Size 

Yes, kibble size is essential when focusing on dental health and eliminating bad breath. By choosing dog foods with larger kibble, with a bit of a curve or “rougher” edges, you can help your dog scrape tartar buildup off their teeth — while they eat! 

Small dogs and dogs with few teeth may do well on a wet food diet or dog foods with small bites. But if that’s the case, brush their teeth more often to make up for the lack of kibble cleaning.

Our Verdict

Your dog doesn’t have to suffer from halitosis (aka smelly breath!). Instead, choose one of the best dog foods for bad breath to protect their teeth, gums, and health. Your dog’s diet plays a big part in dental health, so get them the best option possible. 

Our top choice is Taste of the Wild Pacific Stream Grain-Free dry dog food.  

It’s packed with protein and healthy fats for tooth support. But it also has antioxidants and probiotics, helping to promote good dental health.  

No matter the food you choose, the best dog foods on this list will have your dog’s oral health back to normal in no time.
