Dog Bad Breath: Causes, Prevention, and Treatment

Dog bad breath can be a common issue among pet owners. The unpleasant odor can be a sign of a health problem that needs immediate attention. In this article, we will discuss the causes of bad breath in dogs, how to prevent it, and the possible treatments.

Causes of Dog Bad Breath

Several factors can cause bad breath in dogs. Here are some of the most common ones:

Poor Oral Hygiene

One of the most common causes of bad breath in dogs is poor oral hygiene. Just like humans, dogs need proper dental care to maintain healthy teeth and gums. When dogs don't receive proper dental care, bacteria can accumulate in their mouths, leading to bad breath. Plaque and tartar buildup on teeth can also contribute to bad breath. Poor oral hygiene can be caused by a variety of factors, such as not brushing your dog's teeth regularly or feeding them a diet high in sugary or starchy foods. It's important to take your dog to the vet for regular dental cleanings and to maintain good oral hygiene at home.


A dog's diet can play a significant role in causing bad breath. Feeding your furry friend a diet that is high in carbohydrates or low-quality protein can increase the amount of tartar and plaque buildup in their mouth, leading to bacterial growth that produces bad odor. Additionally, feeding table scraps and human food to your dog can also contribute to bad breath. It's essential to provide your pet with a well-balanced and nutritionally complete diet that meets their dietary needs and is appropriate for their age, breed, and lifestyle. Consult your veterinarian for dietary recommendations and choose premium-quality pet foods that contain high-quality proteins, whole grains, and fiber to promote optimal digestive health and fresh breath.

Digestive Problems

One of the possible causes of bad breath in dogs can be related to digestive problems. When dogs eat something that their digestive system is not able to break down properly, it can lead to bacterial overgrowth in the stomach. This bacterial imbalance can cause bad breath. In addition, dogs who suffer from gastrointestinal disorders such as inflammatory bowel disease or lack of digestive enzymes may also experience bad breath. Some other potential causes of digestive problems causing bad breath may include foreign objects in the gastrointestinal tract, food allergies, or even cancer. Therefore, it is essential to consult with a veterinarian to determine the underlying cause of the digestive issue and begin appropriate treatment.

Dental Issues

One of the most common causes of bad breath in dogs is dental issues. Just like in humans, the accumulation of plaque and tartar can lead to gum diseases, cavities, and tooth decay in dogs. These conditions can create a breeding ground for bacteria that produce foul-smelling compounds. Additionally, if a dog suffers from a broken tooth or a gum injury, it can cause infection and inflammation, which can worsen the odor. Therefore, regular dental care is crucial for preventing dental problems that contribute to bad breath in dogs. Brushing their teeth with a dog-friendly toothbrush and toothpaste, providing chew toys, and scheduling regular dental checkups with a veterinarian can help keep their teeth and gums healthy and their breath fresh.

Medical Conditions

Medical conditions can also contribute to bad breath in dogs. Some of these conditions include diabetes, kidney disease, and liver issues. When these problems arise, they can cause a foul odor in the mouth due to a build-up of toxins in the body. Additionally, gastrointestinal issues such as inflammatory bowel disease or acid reflux can also cause bad breath in dogs. It is important to recognize these medical conditions early on, as prompt treatment can help address both the underlying issue and the accompanying bad breath. Regular check-ups with a veterinarian and proper dental care can help prevent the development of these conditions.


Prevention is key to avoiding dog bad breath. Here are some ways you can prevent it:

Proper Oral Hygiene

Proper oral hygiene is one of the most important steps in preventing dog bad breath. Make sure to brush your dog's teeth regularly with pet-friendly toothpaste. Utilize a toothbrush specifically designed for dogs that fits comfortably in their mouth. Incorporate healthy treats into their diet that aid in dental health and reduce plaque buildup. Avoid feeding your pet table scraps as they can contribute to bad breath and other health issues. Regular check-ups with your veterinarian can also catch any dental or health issues early on before they worsen and cause bad breath. By following these steps and ensuring that your furry friend has good dental hygiene, you can prevent dog bad breath and maintain their overall health.

Regular Check-ups with Your Veterinarian

Regular check-ups with your veterinarian are crucial for preventing dog bad breath. During these appointments, your vet can examine your dog's teeth and gums, check for any signs of dental disease or infection, and recommend a dental care routine that suits your pet's individual needs. This may include brushing your dog's teeth daily, providing them with dental chews or toys, or scheduling professional dental cleanings as needed. By staying on top of your dog's oral health, you can help prevent bad breath and other serious health issues. Additionally, your vet can identify any underlying medical conditions that may be contributing to your dog's bad breath, such as liver or kidney disease, and recommend appropriate treatment. So, make sure to schedule regular check-ups for your furry friend to keep their mouth healthy and their breath fresh.

Dietary Changes

One of the most straightforward ways to prevent bad breath in dogs is by making dietary changes. This includes feeding your furry friend high-quality dog food, which is free from additives, artificial flavors, and preservatives. Additionally, incorporating fresh fruits and vegetables into their diet can help prevent plaque buildup on their teeth, which is a leading cause of bad breath. Providing your dog with a regular supply of clean water is also essential to maintaining good oral health. Some pet owners also prefer to give their dogs dental chews or bones that are designed to help clean their teeth and freshen their breath. By taking these small dietary steps, you can help your dog maintain fresh breath and good oral hygiene.

Provide Toys and Bones for Chewing

One effective way to prevent dog bad breath is to provide your furry friend with toys and bones for chewing. Chewing is a natural behavior for dogs, and it helps clean their teeth and gums. When dogs chew on toys and bones, it stimulates their saliva production, which can help wash away harmful bacteria in their mouth. In addition, chewing can help reduce stress and anxiety in dogs, which can also contribute to bad breath. To keep your dog interested in their chews, try using a variety of textures and flavors. However, be sure to supervise your dog to prevent choking or tooth damage. By providing your dog with appropriate chewing options, you can help them maintain good oral hygiene and avoid unpleasant breath odor.

Monitor Your Dog's Water Intake

Monitoring your dog's water intake is an important aspect of preventing bad breath. Ensuring that your furry friend has access to fresh water at all times is vital, especially during hot weather or after physical activity. Always keep an eye on your dog's water bowl and refill it as needed throughout the day. Also, be mindful of the type of water you're giving your dog. Tap water can contain high levels of chlorine and other chemicals that may contribute to bad breath. Consider using filtered water or purchasing a water fountain specifically designed for pets to keep their water clean and fresh. By monitoring their water intake, you can help prevent dehydration and the development of bad breath.


The treatment for dog bad breath depends on the underlying cause. Here are some possible treatments:

Professional Teeth Cleaning

One effective treatment for dog bad breath is professional teeth cleaning. Veterinarians can conduct a thorough examination of your pet's oral cavity and determine the best course of action to address the problem. The procedure involves the use of specialized tools to remove tartar and plaque buildup on the teeth and gums. It may also require the administration of anesthesia to keep your furry friend calm and comfortable during the cleaning process. In some cases, antibiotics may be prescribed to treat any underlying infections that are causing the bad breath. Professional teeth cleaning can be an essential step in maintaining your dog's overall health and well-being.

Antibiotics for Infections

When bad breath in dogs is caused by bacterial infections, vets may prescribe antibiotics to eliminate the harmful bacteria. Antibiotics can come in various forms, such as pills or topical creams, and they work by killing off the bacteria causing the infection. Depending on the severity of the infection, antibiotics may need to be administered for a few days to several weeks. It is important to follow the dosage and frequency recommended by the vet to ensure the dog completes the full course of treatment. Overuse or misuse of antibiotics can lead to antibiotic resistance, which can make future treatments ineffective. In addition to antibiotics, vets may also recommend other supportive treatments to help improve the overall health of the dog.

Digestive Enzyme Supplements

One possible treatment for dog bad breath is the use of digestive enzyme supplements. These supplements contain beneficial enzymes that help break down food in the digestive system and prevent undigested particles from building up in the mouth, which can cause bad breath. Additionally, these supplements can help improve overall digestion and nutrient absorption. It's important to choose a high-quality supplement that's specifically formulated for dogs and to follow the recommended dosage guidelines. Other possible treatments for bad breath in dogs include dental cleanings, regular toothbrushing, healthy diet and plenty of water. In severe cases, your veterinarian may need to seek further assistance.

Dietary Changes

Dietary changes can be a simple yet effective treatment for dog bad breath, especially if the cause is related to the food they eat. Consult with your veterinarian to determine if your pup needs to switch to a low-protein or high-fiber diet. Offering dental chews or toys that can help control plaque and tartar buildup is also an excellent method to introduce into their daily routine. Additionally, avoiding feeding them human food or table scraps can help prevent bad breath caused by indigestion. A well-balanced diet with plenty of fresh water can go a long way in maintaining your dog's overall health and fresh breath.

Surgery for Dental Issues

If the bad breath in your dog is due to dental issues such as gum disease or tooth decay, surgery may be necessary. The surgery can involve tooth extractions, scaling and root planing, and periodontal flap surgery. Your veterinarian will analyze your dog's dental condition, and decide on the best treatment option. Tooth extractions are usually performed when the tooth cannot be saved, or if the infection has spread to the roots. Scaling and root planing is a deep cleaning procedure that removes plaque and tartar build-up. Periodontal flap surgery involves lifting the gums to access the teeth and remove any infection or decay. Although surgery may sound daunting, it is often the most effective way to resolve dental issues and prevent bad breath. Your veterinarian will discuss the surgery and postoperative care with you in detail.
