Symptom
Bad breath in dogs and cats
Bad breath is not a normal trait of the animal. Most often the source is the oral cavity: dental plaque, gum inflammation, periodontitis, damaged teeth or other dental disease. Sometimes an unusual odour accompanies systemic disorders — that requires a full clinical assessment.
Most common possible causes
- —Dental plaque and tartar
- —Gingivitis and periodontitis
- —Damaged teeth or root disease
- —In cats — tooth resorption (TR) or chronic gingivostomatitis
When not to postpone an exam
- ✓Facial or under-eye swelling has appeared
- ✓The pet refuses to eat
- ✓There is discharge or marked drooling
What not to do at home
- —Do not scrape tartar with sharp objects
- —Do not use human toothpastes, mouthwashes or gels — they are not meant for pets; xylitol in some products is toxic to dogs
What diagnostics may be needed
- ✓Clinical examination
- ✓COHAT under anaesthesia
- ✓Dental radiography
Some inflammatory processes are hidden under the gums. The exact cause can be established only after examination and the necessary diagnostics.
How treatment may proceed
- ✓Professional cleaning
- ✓Periodontal therapy
- ✓Extraction or treatment of teeth when indicated

Frequently asked questions
Persistent bad breath is most often linked to the oral cavity. It can also accompany some systemic diseases, so the animal's overall condition matters too.
