The best step you can take to combat your dog's foul breath is regular teeth cleanings. Severe halitosis in dogs can be indicative of serious health problems, so schedule a veterinary appointment to check for periodontal disease if it's becoming a struggle to stomach kissing your pooch.

“A lot of people just believe that dogs just have bad breath,” Dr. Stephanie Livermore, a veterinarian specializing in dog dentistry at New York City’s Pearly Bites clinic, explains. “They don’t have great breath, but if an owner is smelling a really foul odor that is starting to get more foul, there is a really good chance that there is disease below the gum line.”

But if your dog's dental health checks out, then dog breath fresheners can present an effective way to take the edge off their doggy breath. The best dog breath fresheners don't just cover bad breath but also have positive dental health benefits. Our top pick dog breath freshener combats plaque and tartar, the most common culprits when it comes to periodontal disease.

In addition to breath-freshening treats, our other recommendations include water additives, pastes, and dietary approaches—all of which have been approved by the Veterinary Oral Health Council (VOHC) through clinical trials.

Here are the best dog breath fresheners.

With this line of kibble products from Hill’s, your dog’s daily meal can become a means of counteracting foul breath and dental problems.

The fiber, omega-6 fatty acid, and antioxidant content in the kibble help promote a healthy gut, skin, and coat.

Rather than break apart in the dog’s mouth, the kibble is also designed to scrape against dogs’ teeth to remove plaque and tartar. Despite this toughness, however, it has proven to go down easy for dogs of a variety of breeds and sizes, provided that they don’t already have significant periodontal disease.

What to Look for in Dog Breath Fresheners

Dental Health Benefits

According to Dr. Stephanie Livermore, a veterinarian specializing in dog dentistry at New York City’s Pearly Bites clinic, more than 80 percent of dogs have some form of periodontal disease before the age of 3. In other words, your favorite canine’s gross breath is not something to be taken lightly. Don’t overlook regular treatment of minor dental issues that can develop into something very serious and painful in your dog’s older age. Make sure that when selecting a breath-freshening product, you look for ones that are tackling plaque, tartar, and other detrimental bacteria within your dog’s mouth. Treating bad breath in dogs isn't a matter of making quick fixes but instead about consistent dental hygiene.


As with anything that is coming into contact with your dog’s mouth, it is crucial that you make sure the treat or product you are using is suitable for your size and breed of dog. Be sure to check the intended weight range for the product you choose. If your dog has struggled with or been put off by specific snacks or additives in the past—whether due to texture, hardness, flavor, or another reason—avoid any product that might have a similar taste or toughness.


Most of the breath freshener options we’ve included here contain natural ingredients, and their VOHC endorsements demonstrate that there aren’t many risk factors to speak of with these products. But definitely check out the ingredient list to make sure there’s nothing that you know will disagree with your pup.

  • Can breath fresheners replace brushing my dog’s teeth?

    In short, absolutely not. “The first thing that a pet owner should be doing is having a comprehensive oral health assessment and treatment,” Dr. Livermore explains. VOHC-approved breath fresheners should merely be considered an extension of the important work that doggie dentists and regular teeth cleanings do.

  • Are mint-flavored products safe for dogs?

    Mint-flavored products pose no potential issues safety-wise, but as Dr. Livermore notes, some dogs don’t love the flavor. It may seem unlikely that a savory or meat-flavored product could result in fresher breath for your pup; however, these treats and supplements tackle the issues that cause bad breath at the source. As much as any product boasting minty freshness, they help assure long-term dental health and can potentially be an easier sell for your pup.
