What Causes Bad Breath in Dogs

Many factors work together to give your dog horrible breath. Of course, they are the same things that give humans bad breath, but your dog’s all meat diet and lack of brushing amplifies the problem and make it much more noticeable. 


Bacteria are responsible for most of the bad smells in the world. When it comes to oral health, bacteria forms plaque on your dog’s teeth as it breaks down leftover food bits. The plaque is terrible for your dog’s oral health and can turn their breath putrid. 

If left uncleaned, bacteria can cause many other problems for both you and your dog. It is better to keep the bacteria in check whenever possible through brushing and mouth sprays. 


Tartar is a hard substance that grows on teeth when plaque starts to mineralize. It allows more bacteria to grab on and forms more plaque. It’s a vicious cycle that builds even more tartar. 

Getting rid of tartar will help your dog have a healthier mouth, and it will get rid of places for bacteria to flourish. 

Decomposing Food 

Food can get caught in your dog’s mouth, especially in between the teeth. The pockets of food are breeding grounds for all types of bacteria that release stinky gases as they break down the meat. Removing the food can help ease the smell.

Oral Health Issues 

Problems like gum disease or periodontal disease can cause issues for your bad dog breath. When left unchecked, many of these disorders can cause even more problems for your pet down the line, including pain, other infections, and loss of teeth. 

These inflictions tend to increase the amount of bacteria in the mouth, which is the root cause of all bad breath. Periodontal disease is gum disease that can make dogs really sick.

Why Make Breath Spray at Home? 

You have probably seen many dog breath sprays at the store that you can buy and use on your pet. 

You could buy a commercial dog spray and use that when their breath gets bad. However, there are many advantages to making your own fresh breath spray that will help your dog’s breath and health.  

Better Ingredients 

Commercial products find any way they can to save money and maximize profit. To achieve this, they often use lower-quality materials that deliver similar results. They will use synthetic smells and flavors that can add many chemicals to the spray your dog doesn’t need. 

Many of the store sprays use Xylitol to make it taste better for dogs. Studies show Xylitol may be toxic to your pet. In the homemade dog breath spray, you skip possibly harmful ingredients and use natural alternatives. 

More Effective 

The better materials can work better for your dog. Rather than masking the smell, homemade sprays can kill bacteria and give your dog better oral health. Using real herbs and natural oils makes the spray more potent and better at its job. 

Less Expensive

You can find many of the ingredients in a homemade dog breath spray in your kitchen and garden. There is a minimal upfront cost to making the basic spray. Even if you do have to buy the ingredients separately, you’re not looking at breaking the bank on the process. 

Making the spray is also easy and won’t take you all day. You can do the simple procedure in under 20 minutes once you get used to it.

It’s Not Just For Smell, Benefits of Breath Spray

Dog breath spray doesn’t just make your dog’s breath smell better, though that is a significant benefit. It can also help your dog have better overall oral health. It can help the dog, especially when paired with the rest of an oral hygiene program for your dog

Helps Clean Their Teeth 

Using the spray can help soften tartar build-ups, which can cause them to come off. It can also remove the unwanted film from the teeth, which could have caused other issues for your dog. 

Some owners use the spray in place of brushing the dog’s teeth, and they get fairly good results. It will be up to you to do both or let the spray replace the more complex task of brushing. 

Removes Plaque 

Plaque is one of the quickest things to start building up on your dog’s teeth. If you use the spray regularly, it can keep plaque at a minimum. If the plaque isn’t allowed to grow on your dog’s teeth, you can avoid tartar buildup and many other problems. 

Kills Bacteria 

The herbs and essential oils in the mouth spray help kill bacteria and stop its growth and spread. You can also add vinegar and other bacteria-destroying elements to the spray.  

Killing the bacteria stops the foul smell, but it also eliminates many chemicals that can break down teeth and cause other oral diseases. By getting rid of the source of the problem, you can cut down on many other dangerous side effects, the least of which is bad breath.

You can use as much of this oil as you need to help make your dog’s mouth smell better. It is safe for your dog, and dogs should enjoy the taste due to the glycerin and coconut oil.
