Will Probiotics Help My Dog’s Bad Breath?

Yes, probiotics for dogs bad breath can help.

Since bad breath in dogs is closely related to bacteria imbalances, it is easy to see a new therapeutic opportunity in probiotics. 

Can Probiotics Make Dog Bad Breath Worse?

However, overall, probiotics for dogs bad breath are beneficial. Furthermore, probiotics have other added benefits, including boosting your dog’s immune system, improving GI tract health, and strengthening digestive health. As a result, the overall health of your pet improves, and you end up with a healthy dog.

How do Probiotics for Dog Bad Breath Work?

The good bacteria in probiotic supplements suppress the growth of bad bacteria and decrease the risk of developing oral diseases (plaque and tartar buildup, tooth decay, and gingivitis) that lead to bad breath. 

An interesting 2005 study suggests that transmission of halitosis-causing bacteria from pets to humans might be possible. This finding accents the critical role of specific bacteria in the onset of bad breath. 

If your dog’s breath issues stem from a dental problem, a visit to the vet’s office is more than necessary. The vet will check the dog’s teeth and gums and recommend the best solution – medications (antibiotics or anti-inflammatories), dental cleaning, or both. 

However, if the causes of bad breath are microbial imbalances in the dog’s gut or mouth, it is worth giving probiotics a try. Just keep in mind that good bacteria are not a magic cure – it may take up to several weeks before the effects of the probiotics for dogs bad breath kick in and you notice an improvement.

How Long does it Take for Probiotics to Work in Dogs with Bad Breath?

Probiotics for dogs bad breath can take anywhere from two days to a couple of weeks before they start to show their impact. Oral disease, imbalances in the dog’s gut microbiome, and halitosis are closely related. This is because the dog’s digestive system has many different functions. 

Namely, teeth and gum illnesses are either triggered or result in changes in oral bacteria. When the dog swallows saliva, it also swallows these bacteria, which can colonize the intestines and cause a microbial imbalance. 

On the other hand, if the imbalance starts in the dog’s gut, it can still negatively impact the mouth and culminate in bad breath. In case of an upset stomach, the bad bacteria take control and release foul-smelling chemicals. Then they are absorbed into the bloodstream and exhaled via the breath. 

We should note that halitosis is a problem you can see, but it is not the only one. Infections in the dog’s mouth can quickly spread to distant organs, causing potentially life-threatening kidney disease or heart illnesses. Therefore, using probiotics for dogs bad breath is important. 

How do I Use Probiotics for My Dog’s Bad Breath?

Probiotics for dogs bad breath are an excellent way to freshen up your dog’s breath. However, they are not the only ones. Here are some home remedies you can use to combat halitosis: 

  • Parsley. In addition to being a good source of many nutrients and antioxidants, parsley can be the solution to your dog’s bad breath. However, ensure not to use spring parsley as this variety can be toxic to dogs. 
  • Carrots. Chewing carrots can help your dog’s breath by cleaning the teeth or, simply put, scraping the plaque off the teeth. If your pup is not a fan of carrots, try apples – the effect is the same.  
  • Coconut oil. Coconut oil has antimicrobial properties similar to those of toothpaste. You can add coconut oil to your dog’s food or while brushing your dog’s teeth. Just make sure you implement the coconut oil gradually to prevent an upset stomach. 
  • Apple cider vinegar. The acid in apple cider vinegar is breath-improving as it can kill the bad bacteria in the dog’s mouth. A single teaspoon of apple cider vinegar in the drinking water can do wonders about lousy breaths. 
  • Yogurt. Instead of probiotic supplements, you can use natural probiotic foods like yogurt or even kefir. Greek yogurt is safe for dogs and rich in probiotics like Lactobacillus acidophilus. 
  • Mint. Do you even need any convincing that mint can improve your dog’s breath? Add a few mint leaves to your dog’s water and watch how its breath will improve in no time.
  • Lemon. Just like apple cider vinegar, the high acid concentration in lemons can kill the bad bacteria in the mouth. Lemon juice also acts as a natural deodorizer. 

Adding any of these home remedies in addition to your dog’s probiotics can be a great way to help improve your dog’s breath.

How do I Choose the Best Probiotic for Dog Bad Breath?

Inaccurate labels, false claims, and misleading ads – finding the best probiotics for dogs bad breath can be tricky. To keep the probiotic shopping simple, consider this checklist when shopping for probiotics for dogs bad breath:

  • Different Strains of Bacteria. The right probiotics for dogs bad breath must include various bacteria strains (from the Bacillus, Bifidobacterium, Lactobacillus, and Enterococcus family) with different health effects.  
  • Colony Forming Units. Dogs need between 1 and 4 billion CFU per day for maintenance purposes and general health. Probiotics for dogs bad breath should contain good bacteria within this number range. 
  • No Fillers, Allergens, and GMOs. Ingredients like corn, soy, grains, and dairy should not be included in high-quality probiotics for dogs bad breath.
  • Added Ingredients. Opt for probiotics for dogs bad breath enriched with nutrients like prebiotics, digestive enzymes, vitamins, and mineral for more health-boosting effects.
