Why small breed dogs are prone to dental disease
Dental disease is the most common health problem in small breed dogs. By age three, most toy and small breeds have some form of periodontal disease. The main reason is their mouth anatomy: small jaws have the same number of teeth as large breeds, leading to overcrowding. This traps food and plaque, accelerating tartar buildup. Genetics also play a role. Breeds like Chihuahuas, Yorkshire Terriers, Pomeranians, and Dachshunds are especially predisposed. Without intervention, dental disease progresses from gingivitis to periodontitis, causing pain, infection, and tooth loss.
Signs of dental disease in small dogs
Dogs often hide pain, so you must look for subtle signs:
– Bad breath (halitosis) that doesn’t go away
– Yellow or brown tartar on teeth, especially near the gumline
– Red, swollen, or bleeding gums
– Dropping food, chewing on one side, or reluctance to eat hard kibble
– Pawing at the mouth or facial swelling
– Loose or missing teeth
– Changes in behavior: irritability, lethargy, or hiding
If you notice any of these, schedule a veterinary dental exam. Do not try to scrape tartar yourself , it can damage enamel and gums.
Professional treatment options
Only a veterinarian can diagnose and treat dental disease. Treatment depends on the stage:
Stage 1 (Gingivitis): Professional dental cleaning under anesthesia, with scaling and polishing. Your vet will also check for pockets and early bone loss.
Stage 2-3 (Periodontitis): Deep cleaning above and below the gumline. If pockets are greater than 4mm, your vet may recommend a dental X-ray to evaluate bone loss. Some teeth may need extraction if too damaged.
Stage 4 (Advanced periodontitis): Extraction of severely affected teeth, often multiple at once. Antibiotics and pain medication may be prescribed. After healing, your dog will adapt , small breeds eat well even without some teeth.
Important: Anesthesia-free dentistry is ineffective and risky for small dogs. It misses subgingival tartar and can cause fear or injury. Always choose a vet who uses anesthesia and does full mouth X-rays.
At-home prevention: what you can do
Prevention is far better than treatment. Small dogs need daily care:
Brushing: Use a pet-safe toothbrush (finger brush or small head) and enzymatic toothpaste (never human toothpaste , harmful if swallowed). Brush at least every other day, ideally daily. Start slowly, reward with a treat.
Dental chews and toys: Look for VOHC-accepted products that reduce plaque. Choose appropriately sized chews to avoid choking. Examples include CET chews, Greenies, or dental toys like rubber textured bones. Avoid hard nylon or real bones , they can fracture small teeth.
Water additives and gels: Products like Oxyfresh or HealthyMouth can help reduce bacteria. They aren’t a substitute for brushing but add extra protection.
Diet: Some veterinary prescription dental diets (like Hill’s t/d or Royal Canin Dental) have kibble that mechanically scrubs teeth. Ask your vet if they’re right for your dog.
Regular vet checkups: Annual dental exams and cleanings as recommended (often every 6-12 months for small breeds).
When to call the vet
If your dog shows any signs of pain, stops eating, has facial swelling, or if you see bleeding from the mouth, contact your vet immediately. Dental infections can spread to the heart, liver, or kidneys. For routine dental care, schedule a professional cleaning whenever tartar buildup is visible or your vet advises. Small dogs may need cleanings more frequently than large breeds.
Remember: you are your dog’s advocate. With consistent home care and professional oversight, you can prevent dental disease and keep your small breed’s smile healthy for years.
Key Takeaway
Prevent dental disease in small breed dogs with daily brushing, VOHC-approved chews, and regular veterinary cleanings under anesthesia.
