What Causes Bad Dog Breath?

Before you reach for a breath freshener or book a professional cleaning, it’s important to understand where that smell is coming from. Bad breath in dogs can have several causes—from poor hygiene to more serious health issues.

Poor Dental Hygiene

The most common reason your dog’s breath stinks? Plaque and tartar buildup. When bacteria accumulate in your dog’s mouth, they create a film over the teeth and gums. Without regular brushing, this hardens into tartar—causing bad odor, gum disease, and even tooth loss.

Signs of poor dental hygiene include:

Diet & Chewing Habits

Sometimes, the issue lies in what your dog is eating—or not chewing. Low-quality food, table scraps, and lack of chew toys can all contribute to foul breath. If your dog isn’t chewing enough, food particles can sit in the mouth and rot—causing odor and encouraging bacteria growth.

Here are some of the most common culprits:

• Highly processed kibble;
• Sticky, grain-heavy treats;
• No access to natural chews or dental toys.

Underlying Health Issues

In some (rarer) cases, bad breath is more than a grooming issue—it’s a symptom of something deeper. Sometimes, it can be a matter of your dog being genetically predisposed to dental disease (e.g., periodontal disease, enamel dysplasia, and/or malocclusion). In rare cases, serious conditions like kidney disease, liver problems, or diabetes can be the cause of distinct and persistent odors.

So, we recommend always keeping an eye out for:

• Sweet or fruity-smelling breath (may indicate diabetes);
• Ammonia-like odor (possible kidney issue);
• Yellowing eyes or gums (potential liver problem).

If your dog’s breath suddenly changes or worsens, contact your vet for a dental assessment..

How to Fix Bad Dog Breath at Home

Now that you know what’s causing the stink, let’s talk about how to fix bad dog breath—starting with the most effective DIY solutions.

Brushing Your Dog’s Teeth

Yes, you really can (and should) brush your dog’s teeth at home! It’s one of the most effective ways—if not THE most effective way—to reduce bacteria and odor.

“Brushing your pet's teeth is a great way to maintain their dental health in-between professional cleanings.” —Nadia Bongelli, industry leader, educator, and award-winning dog groomer

What You’ll Need:

Having the right tools on hand will make brushing your dog’s teeth easier and more effective.

✔️ A dog-specific toothbrush (finger brushes work great for beginners).

✔️ Enzymatic dog toothpaste (NEVER use human toothpaste).

✔️ Treats for positive reinforcement.

Step-By-Step:

Follow these simple steps to help your dog get comfortable with brushing and keep their mouth clean and odor-free!

Dog Dental Food & Treats for Bad Breath

Wondering what you can give your dog for bad breath? Dog dental treats and specially formulated dental food are easy, vet-approved options that help clean teeth and freshen breath—right through chewing.

Here’s what to look for in dental treats or dog dental food:

✔️ Have a VOHC (Veterinary Oral Health Council) seal.

✔️ Are designed to scrape plaque as your dog chews.

✔️ Contain breath-freshening ingredients like chlorophyll or parsley.

Some popular options include:

• Greenies Dental Treats
• Whimzees Natural Chews
• Zuke’s Z-Bone
• Hill’s Prescription Diet t/d Dental Care Dog Food
• Royal Canin Dental Dry Dog Food

⚠️ ALWAYS check with your vet before switching your dog’s food or introducing new treats, especially if your dog has dietary restrictions or health concerns. And remember: treats are helpful, but they’re NOT a replacement for brushing!

Water Additives & Dental Toys

If brushing isn’t your dog’s thing (yet), water additives and dental toys are great alternatives. They help control bacteria and stimulate chewing—both of which improve breath.

Water Additives:

Water additives are an easy, no-fuss way to freshen your dog’s breath and support oral health between brushings. Often flavorless and odorless, simply add them to your dog’s water bowl daily to help combat plaque and odor.

Dental Toys:

Dental toys are designed to clean your dog’s teeth while they chew, making them a fun and effortless way to support oral health. Look for toys made from textured rubber or durable nylon, as these materials help scrub away plaque. Many can also be stuffed with dog-safe toothpaste or spreadable treats to keep your pup engaged while promoting fresher breath.

DIY Home Remedies

Looking for a dog bad breath home remedy that’s gentle and effective? Here are a few natural options pet parents swear by:

• Coconut oil: Contains antibacterial properties. Offer ½ tsp daily for small dogs, 1 tsp for larger breeds.
• Fresh parsley: Chop finely and mix into meals for a chlorophyll boost.
• Carrots and apples: Crunchy, low-calorie snacks that help clean teeth naturally.

⚠️ ALWAYS consult your vet before introducing new supplements—especially if your dog has allergies or health concerns.

When to Worry About Your Dog’s Breath

As we briefly mentioned earlier, sometimes, bad breath is more than a grooming issue. Here's how to know when it might be time to call the vet.

Signs It’s a Health Concern

If your dog’s breath suddenly changes in smell, intensity, or is accompanied by other symptoms, take note. It could indicate a deeper problem.

When to See a Vet

Schedule a check-up if:

• Your dog’s breath smells “off” even with regular care;
• You see visible signs of dental decay;
• Your dog is acting differently (tired, not eating, etc.);
• You’re unsure whether it’s a grooming or medical issue.

In cases such as this, a professional cleaning may be necessary to remove hardened tartar and evaluate your dog’s overall oral health.

Preventing Bad Breath Going Forward

The best way to deal with bad breath? Stop it before it starts! Consistent care at home keeps your dog’s breath fresh—and their overall health in check.

Daily Routines to Try

Here’s how to keep your dog’s mouth in tip-top shape:

✅ Brush 2–3 times per week (daily if possible)
✅ Offer a dental chew or toy daily
✅ Add a water additive to your dog’s bowl
✅ Wipe the mouth area after meals to reduce bacteria buildup

Healthy Diet Tips

A healthy diet plays a big role in oral hygiene. Some commercial foods leave residue or contain sugar that feeds mouth bacteria. Natural diets with whole ingredients, on the other hand, can reduce odor and improve overall wellness.

So, consult with your vet about switching your dog to a diet that contains:

• High-quality kibble with limited fillers;
• Raw vegetables like carrots for snacks;

Just make sure you don’t change your dog’s diet until you get the go-ahead from your veterinarian. In addition, it’s also important to avoid giving your dog table scraps, sugary treats, and sticky foods. 

Regular Vet Visits

While you can handle most grooming tasks at home, regular checkups with your vet are still essential for your dog’s overall health. Your vet can:

• Check for underlying issues that may cause bad breath;
• Perform professional dental cleanings when needed;
• Monitor for signs of infection, decay, or oral disease.

Pairing consistent at-home grooming with routine vet care is the BEST WAY to keep your dog happy, healthy, and smelling fresh—no salon required!
