Bad Breath in Dogs

Vets refer to bad breath (foetor ex ore or halitosis) when it lasts over a longer period. Short-term odor after eating is normal. Persistent mouth odor, on the other hand, almost always has a cause: most of them can be treated well.

11 Causes of Bad Breath

1. Diseases in the mouth

Inflammation of the tooth root or other mouth structures can cause foul odors. Usually harmless, but painful: a vet should clarify the cause.

2. Tartar and periodontitis

Periodontitis is a common cause. With the right treatment at the vet, the bad breath can usually be eliminated completely.

3. Gum inflammation (gingivitis)

In the early stage, mouth odor is often the only symptom. See the vet if bad breath persists. Left untreated, the advanced stage brings:

• Bloody saliva
• Pus deposits
• Weight loss
• Bouts of fever
• Pain in the mouth, one-sided chewing reflexes
• Loose teeth, tooth loss

4. Gastritis (stomach lining inflammation)

Excess stomach acid leads to a sour, rotting bad breath. Accompanied by: loss of appetite, vomiting, diarrhea and weight loss.

5. Diseases of the esophagus

With megaesophagus, the esophagus is enlarged. Alongside bad breath, vomiting, pneumonia, increased coughing and fever occur.

6. Swallowed foreign objects

Swallowed or inhaled foreign objects produce a rotten, decay-like smell. The longer they go unnoticed, the stronger the stench: and the higher the risk of inflammation.

7. Inflammation of the nasal lining and sinuses

Caused by viruses, bacteria or fungi. Accompanying symptoms:

• Runny nose and sneezing
• Blocked or dripping nose
• Watery or pus-filled nasal mucus
• Difficulty swallowing

Drug treatment is necessary: see the vet.

8. Tumors in the mouth or nose area

A rare cause, especially in older dogs. Cell damage and inflammation from the tumor cause the smell.

9. Diabetes

Diabetic bad breath often smells sweet and fruity. Other symptoms: increased drinking and urination, intense hunger, weight loss, lethargy, poor wound healing.

10. Diseases of the urinary tract

An intense, urine-like bad breath can point to kidney problems or diseases of the urinary tract. Since these can become life-threatening, a vet visit is absolutely necessary.

11. Liver diseases

The liver detoxifies the blood and controls metabolic processes. If these functions are impaired, harmful substances build up and cause bad breath. Accompanying symptoms:

• Light gray stool, jaundice
• Behavioral changes (aggression, confusion, restlessness)
• Bloated belly
• Increased thirst and urination

When to see the vet?

Bad breath is usually harmless. But if other symptoms appear: especially a urine-like, rotten or decaying smell: see the vet right away. Better once too often than too late.

How Do I Get Rid of Bad Breath?

If the vet can't find any disease, the cause usually lies in a poor diet or a lack of dental care.

The right dog food

Low-quality food promotes tartar buildup and damages the tooth surface. Specially developed products that reduce tartar can make a real difference.

Treats and chews

Low-sugar treats and high-quality chews promote dental hygiene. Chew roots and chew antlers are considered especially good options. Low-quality chew toys, on the other hand, can make bad breath worse.

Toys for dental health

Pet stores carry play items that reduce tartar and deposits and lessen mouth odor.

Brushing teeth

Brushing teeth works for dogs: if they tolerate it. With the right products and a tasty toothpaste, it's often accepted without any trouble. When introduced without pressure, most dogs get used to it.

Food supplements

Food supplements with mouth-care ingredients are available in pet stores. Check the reviews and ingredients beforehand.

What Makes More Sense Than Home Remedies for Bad Breath

Home remedies are often overrated for bad breath. The smell usually doesn't come from simply lacking a fresh scent, but from tartar, gum inflammation or another cause.

That's why this order makes more sense:

1. Check the mouth
2. Brush the teeth, or have them brushed
3. Have tartar removed by the vet
4. Check food and chews

If you want to add anything at all, keep it simple and without big promises of a cure:

• Keep an eye on water intake
• Use sugar-free chew products
• Use dog toothpaste instead of kitchen home remedies
