Why Chewing Is Nature's Toothbrush for Dogs
Long before the invention of toothbrushes and dental wipes, dogs kept their teeth clean through natural chewing behavior. When a dog gnaws on a tough, textured surface, several things happen that benefit oral health:
- Mechanical abrasion: The scraping action of a chew against tooth surfaces physically disrupts and removes plaque biofilm before it mineralizes into hardened tartar.
- Saliva stimulation: Vigorous chewing triggers increased saliva production. Canine saliva contains enzymes like lysozyme and lactoferrin that have natural antibacterial properties.
- Gum massage: The pressure and texture of chewing stimulates blood flow to the gingival tissues, promoting healthier gums and reducing inflammation.
According to the American Veterinary Medical Association (AVMA), periodontal disease is the most common clinical condition affecting adult dogs, with over 80% of dogs showing signs by age three.
Types of Dental Chews and Toys: A Complete Guide
Raw Bones
Raw, meaty bones (never cooked) have been used for generations as natural dental aids. The gnawing action scrapes teeth clean. Best for: Medium to large dogs. Safety: Raw bones can carry bacteria like Salmonella. Always supervise and discard once the bone becomes small enough to swallow whole. Weight-bearing bones from large livestock are too dense and risk tooth fractures.
Bully Sticks (Pizzles)
Made from dried bull muscle, bully sticks are single-ingredient, highly digestible chews that break down in the stomach. They are firm enough to provide mechanical cleaning but softer than bones or antlers. Calorie note: A single 6-inch bully stick contains roughly 80-100 calories. Best for: Small to medium dogs; choose thicker cuts for power chewers.
Yak Chews (Himalayan Chews)
Traditional Nepalese-style hard cheese chews made from yak and cow milk. They are lactose-free and provide a hard, long-lasting chewing surface. Microwave the small leftover piece for a crunchy puff treat. Best for: Moderate to aggressive chewers. Safety: Very dense - avoid for dogs with weak teeth.
Antlers
Deer and elk shed antlers naturally. They are extremely hard and long-lasting. However, veterinary dental specialists frequently warn that antlers are among the top causes of slab fractures (cracked teeth) in dogs. The American Veterinary Dental College advises caution: if you cannot dent an antler with your thumbnail, it is harder than your dog's enamel. Best for: Only the most aggressive power chewers, with strict supervision.
VOHC-Approved Dental Chews
The Veterinary Oral Health Council (VOHC) is the gold standard for dental product claims. Products bearing the VOHC seal have undergone rigorous clinical trials demonstrating measurable plaque and tartar reduction. Brands like Hill's Prescription Diet t/d, Purina Pro Plan Veterinary Diets Dental Chews, and Greenies carry this distinction. Best for: Daily use as part of a complete oral care routine.
Rubber Toys (Kong, Nylabone Types)
Rubber and nylon chew toys serve dual purposes: they satisfy the instinct to chew and can aid dental health when designed with nubs, ridges, and bristle-like protrusions. Kong Classic: Great for stuffing with kibble or dental treats. Nylabone Dental Dinosaur: Nylon bones with raised nubs that act as dental flossers. Which actually help: Toys with raised dental nubbins that contact tooth surfaces provide real benefit. Smooth rubber balls are primarily entertainment.
Rope Toys
Cotton or nylon rope toys can mechanically floss between teeth when the dog chews and pulls. A 2016 study in the Journal of Veterinary Dentistry found that rope toys reduced plaque and calculus on molar teeth when used regularly. Safety: Always supervise - dogs can ingest loose fibers.

Chew Recommendations by Dog Size
Small Breeds (under 25 lbs)
Light chewers: VOHC-approved dental chews (small), bully sticks (thin/4-inch), small Kong rubber toys, soft rope toys. Strong chewers: Yak chews (small), Nylabone Puppy/Dental. AVOID: Antlers, large raw bones.
Medium Breeds (25-55 lbs)
Light to moderate chewers: Bully sticks (standard 6-inch), medium Kong Classic, VOHC dental chews (medium/large), yak chews (medium). Strong chewers: Kong Extreme, Nylabone DuraChew, split elk antler (supervised). AVOID: Weight-bearing beef bones.
Large Breeds (55-90 lbs)
Moderate chewers: Large Kong Classic or Extreme, jumbo bully sticks, large VOHC dental chews, thick yak chews. Power chewers: Kong Extreme (black), Nylabone DuraChew Textured, split elk antler (supervised). AVOID: Thin chews that can be swallowed whole.
Giant Breeds (90+ lbs)
All chewers: Giant Kong Extreme, jumbo Nylabone DuraChew, whole elk or moose antler (split, supervised), Himalayan yak chews (XL). Best daily option: Large VOHC dental chews for giant breeds.
Which Toys Actually Help
Toys with proven dental benefit:
- VOHC-accepted products (clinical trials demonstrate plaque/tartar reduction)
- Kong-style rubber toys stuffed with dental treats (sustained chewing provides 20+ minutes of mechanical abrasion)
- Nylabone Dental series with raised nubs
- Rope toys used regularly (peer-reviewed study evidence)
- Dental-specific chews with ridges and textured surfaces
Toys that are primarily entertainment:
- Smooth rubber balls and tennis balls (minimal tooth contact)
- Plush squeaky toys (no abrasive surface)
- Flat frisbees (caught, not chewed)
- Hard plastic toys without texture
Understanding VOHC Approval
The Veterinary Oral Health Council (VOHC) was established by the American Veterinary Dental College (AVDC) and the Academy of Veterinary Dentistry (AVD). Products that earn the VOHC seal have passed controlled feeding trials demonstrating statistically significant reduction in plaque and/or calculus accumulation. As of 2026, fewer than 50 products worldwide carry this distinction. You can verify current accepted products at vohc.org.
The Big Picture: Chews Work Alongside Daily Wiping
Here is the critical message: Chews alone are not enough to maintain optimal dental health. No matter how well your dog chews, there are surfaces - particularly along the gumline, between teeth, and on inner surfaces - that chews cannot reach effectively.
This is where daily finger wipes and dental powders come in. Think of chews as the mechanical rough-in and daily wiping as the finish work.

Frequently Asked Questions
Are antlers safe for dogs to chew?
Veterinary dental specialists generally advise against antlers for most dogs. The American Veterinary Dental College notes that antlers are harder than tooth enamel and are a leading cause of slab fractures. If you do choose to offer antlers, select split antlers (slightly softer), limit sessions to 15 minutes, and inspect teeth afterward.
Are bully sticks fully digestible?
Yes, high-quality bully sticks are made from 100% beef muscle and are fully digestible. They break down in the stomach's acid environment. However, dogs who gulp down large pieces may experience gastrointestinal upset. Always choose a bully stick larger than your dog's mouth opening and supervise.
How often should I replace dental chews and toys?
Bully sticks and edible chews: Replace when they become small enough to swallow. Yak chews: Replace when down to a 1-inch nub (microwave for a crunchy treat). Rubber toys: Inspect weekly - replace when you see cracks or missing pieces. Rope toys: Replace as soon as fraying begins. Antlers: Replace when edges become sharp.
Can dental chews replace professional veterinary dental cleanings?
No. Dental chews and at-home care reduce plaque and tartar accumulation but cannot remove established calculus below the gumline. Only professional veterinary dental cleaning under anesthesia can address subgingival disease. The AVMA recommends annual veterinary dental examinations for all dogs.
What does the VOHC seal actually mean?
The Veterinary Oral Health Council evaluates dental products based on rigorous clinical trials. Products carrying the VOHC Accepted seal have demonstrated measurable, statistically significant plaque and/or tartar reduction in controlled feeding studies. Look for the seal on product packaging or verify at vohc.org.
My dog is a senior - are dental chews still safe?
Senior dogs benefit enormously from dental care. Choose softer chews appropriate for aging teeth and gums. VOHC-approved dental chews designed for seniors are ideal. Avoid antlers, hard nylon chews, and dense raw bones. For seniors with missing teeth, RunyePet Dental Finger Wipes are gentle enough for sensitive mouths.
How many calories are in dental chews?
A typical VOHC-approved dental chew contains 50-150 calories. Bully sticks range from 80-200+ calories. Yak chews average 50-70 calories per ounce. Factor chew calories into your dog's total daily intake and reduce meal portions accordingly if weight management is a concern.
