5 Tips for Getting Rid of Your Dog’s Bad Breath

Bad breath in dogs is one of the most common complaints pet owners bring up, and it’s more than just an unpleasant odor. If you’re wondering how to get rid of bad breath in dogs, consistent dental care combined with regular veterinary checkups is the most effective approach. Dog bad breath is usually caused by a buildup of bacteria in the mouth, and the good news is that there are practical, vet-approved steps you can take to address it. Read on to learn what causes bad breath in dogs, when it signals something more serious, and exactly what you can do to help.

What Causes Bad Breath in Dogs?

Before diving into solutions, it helps to understand why your dog has bad breath in the first place. Most cases of dog bad breath (sometimes called halitosis) stem from the same basic issue: bacteria. When food particles and bacteria accumulate in your dog’s mouth, they form plaque. Over time, plaque hardens into tartar, which creates an environment where odor-producing bacteria thrive.

That said, not all causes of bad breath in dogs are dental. Other contributing factors can include:

• Diet: Certain foods can temporarily affect breath odor
• Gastrointestinal issues: Gas or digestive problems can produce unpleasant odors
• Kidney disease: A distinctive ammonia-like smell may indicate kidney problems
• Diabetes: A sweet or fruity odor to the breath can be a warning sign
• Oral infections or abscesses: These can produce a notably foul smell

If your dog’s bad breath has come on suddenly, has a very strong or unusual odor, or is accompanied by other symptoms like vomiting, changes in appetite, or excessive thirst, it’s time to schedule a visit to your veterinarian.

When Dog Bad Breath Is a Warning Sign

Persistent bad breath in dogs should never be written off as normal. While some odor after eating is expected, chronic or worsening halitosis often indicates that something needs veterinary attention. At McKean Veterinary Hospital, our team can help identify whether your dog’s breath issues are purely dental or point to an underlying health condition. Early detection makes a significant difference in treatment outcomes.

Tip 1: Schedule Regular Professional Dental Cleanings

One of the most impactful things you can do to eliminate bad breath in dogs is to schedule regular professional dental cleanings with your vet. A professional cleaning goes far beyond what any at-home brushing can accomplish, it removes tartar buildup above and below the gumline, where bacteria thrive and cause the most damage.

During a professional dental cleaning, your dog will be placed under general anesthesia so our veterinary team at McKean Veterinary Clinic can thoroughly clean each tooth, probe the gums for signs of disease, and take dental X-rays if needed. This allows issues like tooth root abscesses, bone loss, or hidden infections to be identified and treated before they become serious and before they contribute to worsening dog breath.

How often your dog needs a professional cleaning depends on breed, age, and individual dental health. Your veterinarian at McKean Veterinary Hospital can recommend the right schedule for your pet.

Tip 2: Brush Your Dog’s Teeth Regularly

Brushing your dog’s teeth is the gold standard for at-home dental care and it’s one of the most effective ways to get rid of bad breath in dogs between professional cleanings. Daily brushing is ideal, though even a few times per week can make a meaningful difference in controlling the bacteria that cause dog halitosis.

Getting Started with Tooth Brushing

If your dog isn’t used to having their teeth brushed, introduce the process slowly. Use a toothbrush designed for dogs, either a finger brush or a standard dog toothbrush, along with a dog-safe enzymatic toothpaste. Never use human toothpaste, as ingredients like xylitol and fluoride are toxic to dogs.

Start by letting your dog sniff and lick the toothpaste. Then gradually work up to brushing a few teeth at a time, always rewarding calm behavior. Focus on the outer surfaces of the teeth where tartar tends to accumulate most. Consistency is key. The more you make brushing a routine, the more cooperative your dog is likely to become.

Tip 3: Provide Dental Chews and Toys

Dental chews and specially designed chew toys can be a useful supplement to brushing when it comes to managing dog bad breath. Certain products carry the Veterinary Oral Health Council (VOHC) seal of approval, meaning they’ve been tested and shown to reduce plaque or tartar, which are the primary contributors to bad breath in dogs.

Look for:

• VOHC-approved dental chews
• Rubber chew toys with ridges designed to clean teeth
• Rope toys, which can have a mild flossing effect on the teeth

While these products can help reduce odor and slow plaque buildup, they are not a substitute for brushing or professional dental cleanings. Think of them as part of a well-rounded dental care routine rather than a standalone fix for dog bad breath.

Tip 4: Evaluate Your Dog’s Diet

What your dog eats can directly influence the smell of their breath. Some wet foods, certain treats, or table scraps can temporarily worsen bad breath in dogs by leaving residue on the teeth and encouraging bacterial growth. A diet of high-quality dry kibble may help reduce plaque buildup to some degree, though diet alone won’t eliminate dog halitosis caused by dental disease.

If you’re concerned about how your dog’s diet might be contributing to their breath, talk to your veterinarian. Our team at McKean Veterinary Hospital can help you evaluate your dog’s current nutrition and recommend any adjustments that support both overall health and oral hygiene.

Tip 5: Don’t Skip Annual Wellness Exams

Annual or biannual wellness exams are one of the best tools for staying ahead of the dental issues that cause dog bad breath. During a routine exam, your veterinarian will assess your dog’s oral health, identify early signs of dental disease, and recommend a dental cleaning if needed before the problem progresses.

Regular checkups also allow your vet to catch systemic conditions that can manifest as bad breath like kidney disease, liver problems, or diabetes, at an earlier, more manageable stage. Getting rid of bad breath in dogs sometimes requires addressing what’s happening inside the body, not just inside the mouth.
