What is halitosis in dogs? 

Halitosis in dogs refers to persistent bad breath. This problem, though common, should not be ignored, as it can be a sign of more serious health issues. Understanding what halitosis in dogs is is essential to treating it effectively.

Causes of halitosis in dogs

Identifying the causes of halitosis in dogs is crucial to finding the appropriate solution. Below, we detail some of the most common causes.

Poor oral hygiene

Poor oral hygiene is one of the main causes of bad breath in dogs. The accumulation of plaque and tartar on the teeth can lead to infections and the production of bad odors.

Poor eating habits can also contribute to bad breath in dogs. Low-quality food, human food scraps, and an inadequate diet can be determining factors.

Diseases that cause bad breath in dogs: Oral disorders

Symptoms:

- Red or inflamed gums

- Bleeding gums

- Loose teeth

- Pain when chewing

- Loss of appetite

Diagnosis and Treatment: Diagnosis is made through a complete dental examination and X-rays. Treatment includes professional dental cleaning, extraction of damaged teeth, and, in some cases, periodontal surgery. It is crucial to maintain good oral hygiene at home through regular brushing and the use of dental products recommended by the veterinarian. 

Gingivitis

Gingivitis is an inflammation of the gums that, if left untreated, can progress to periodontal disease. It is a frequent cause of halitosis in dogs.

Symptoms:

- Red and inflamed gums

- Bleeding gums

Diagnosis and Treatment: Diagnosis is made during a dental examination. Treatment includes professional dental cleaning and establishing a home dental hygiene routine to prevent recurrence.

Symptoms:

- Mouth ulcers

- Pain when chewing
