My dog has bad breath, what should I do? Bad breath in dogs, known as halitosis, often points to dental problems but can also indicate underlying health issues. Identifying the cause helps you choose the right solution for your dog.
What are the most common causes of bad breath in dogs?
In most cases, bad breath in dogs comes from:
- Tartar buildup on the teeth
- Gingivitis (inflammation of the gums)
💡 Maintaining good dental hygiene helps prevent these issues.
Why is tooth brushing so important?

Brushing your dog’s teeth daily is the most effective way to prevent tartar buildup and gingivitis.
However:
- If your dog already suffers from gum inflammation, brushing will feel very uncomfortable.
- In that case, schedule a veterinary visit before starting dental care at home.
When should you consult your veterinarian?
If your dog has severe tartar buildup or advanced gingivitis, your veterinarian may recommend a complete dental cleaning under general anesthesia. This procedure removes plaque and tartar and relieves gum inflammation. After the cleaning, you can safely begin daily brushing to maintain good oral health.
What other options help prevent tartar buildup?
Along with tooth brushing, several products can help reduce tartar formation:
- Dental chews
- Water or food additives
- Dental wipes
- Dental gels
- Enzymatic toothpastes specially made for dogs
- Veterinary dental diets (kibble with a larger size and higher fiber content that helps mechanically clean the teeth)
💡 These products are available at our veterinary clinics. Ask our team for advice on choosing the best options for your dog.
Can bad breath signal other health problems?
If bad breath continues despite good dental care, it may signal a medical issue such as:
- Kidney disease
- Liver disease
- Diabetes
In these cases, your veterinarian may recommend a complete health checkup and blood tests to identify the problem.
Conclusion: what should I do if my dog has bad breath?
When your dog has bad breath, do not ignore this symptom. Good dental hygiene, proper nutrition, and regular veterinary care will help protect your dog’s oral health and detect any underlying health issues early.
