Best Dental Chews for Dogs 2025
Quick Picks to Prevent the $3,000 Veterinary Dental Bill
Most dog owners don't realize their pet's mouth harbors bacteria levels comparable to a garbage disposal until they face a $3,000 veterinary dental procedure. By age three, 80% of dogs show signs of dental disease that could have been prevented with proper dental chews.
The difference between dogs who receive regular dental care and those who don't isn't just about fresh breath—it's about preventing heart, liver, and kidney damage caused by oral bacteria entering the bloodstream.

The Science Behind Effective Dental Chews
Dental chews work through mechanical abrasion—the chewing action physically scrapes away plaque before it hardens into tartar. However, not all chews are created equal. The Veterinary Oral Health Council (VOHC) has established specific criteria for products that genuinely improve oral health.
Key Mechanisms of Plaque Removal
Texture and Shape: Effective dental chews have specific textures that create friction against teeth. Ridged surfaces work better than smooth ones, while the chew must be firm enough to require significant jaw work but not so hard it risks breaking teeth.
Chewing Time: Research shows dogs need at least 5-7 minutes of active chewing to see dental benefits. Chews consumed too quickly provide minimal oral health improvement.
Chemical Action: Some dental chews contain enzymes that break down bacteria or ingredients that help control tartar formation. However, mechanical action remains the primary benefit.
VOHC Approval Matters
Only products that demonstrate at least 10% reduction in plaque or tartar through clinical trials receive VOHC approval. This independent certification is your best guarantee of effectiveness.

Choosing the wrong size dental chew creates safety risks and reduces effectiveness. Chews that are too small pose choking hazards, while oversized options may be rejected or cause jaw strain.
Size Selection by Weight
- Petite (5-15 lbs): Smallest available size, often designed for toy breeds
- Small (15-25 lbs): Most popular size for terriers and small mixed breeds
- Medium (25-50 lbs): Suitable for most popular breeds including Labs and Goldens
- Large (50-100 lbs): Designed for German Shepherds, Rottweilers, and similar breeds
- Extra Large (100+ lbs): For giant breeds like Great Danes and Mastiffs
Choking Prevention
Always supervise the first few uses of any new dental chew. If your dog typically swallows treats whole, dental chews may not be appropriate without training to encourage slower consumption.
Ingredients to Avoid and Safety Considerations
Not all dental chews are safe. Some ingredients and manufacturing processes create unnecessary risks that outweigh potential benefits.
Red Flag Ingredients
Avoid These Components:
- BHA/BHT: Synthetic preservatives linked to health concerns
- Propylene Glycol: Unnecessary additive that can cause digestive upset
- Artificial Colors: Serve no health purpose and may cause sensitivities
- Excessive Sugar: Counterproductive to dental health goals
- Unnamed By-Products: Unknown protein sources of questionable quality
Manufacturing Quality Indicators
Look for products made in facilities with AAFCO feeding trial compliance, USDA inspection, or similar quality certifications. Avoid dental chews from facilities with recent FDA warnings or recalls.
What Veterinary Dentists Actually Recommend
Board-certified veterinary dentists emphasize that dental chews are supplemental to, not replacements for, professional dental care. However, they can significantly extend time between professional cleanings.
Professional Guidelines
Daily Use Protocol: Most effective when given at the same time daily, preferably when dogs are alert and interested in chewing rather than simply swallowing.
Monitoring Progress: Veterinarians recommend dental examinations every 6-12 months to track the effectiveness of at-home dental care including chews.
Combination Approach: The most successful dental care combines appropriate chews with periodic brushing and professional cleanings as needed.
Frequently Asked Questions About Dog Dental Chews
Daily use provides optimal benefits for most dogs. Clinical studies showing plaque reduction are based on daily consumption. However, adjust frequency based on your dog's total caloric needs to prevent weight gain.
No. Dental chews help maintain oral health between professional cleanings but cannot remove tartar that has already formed below the gumline. Most dogs still need professional dental care every 1-3 years depending on genetics and diet.
This eliminates the dental benefits and may pose choking risks. Try using puzzle feeders to slow consumption, offering chews during calm periods, or switching to larger sizes that require more chewing effort.
Brachycephalic breeds (flat-faced dogs) may have difficulty with some dental chews due to breathing restrictions. Senior dogs with dental disease should use softer options. Always consult your veterinarian for breed-specific recommendations.
Yes. Puppies should use softer chews designed for developing teeth and smaller mouths. Avoid very hard chews that could damage developing permanent teeth. Most dental chews are formulated for dogs 6 months and older.
