Best Dental Chews for Small Dogs With Bad Breath (2026)
Why Small Dogs Get Bad Breath Worse Than Large Dogs
Small breeds have disproportionately bad dental disease. Their teeth are crammed into a smaller mouth, so plaque accumulates faster, gums recede sooner, and gingivitis sets in earlier. By age 3, most small dogs already show signs of periodontal disease — the smell from those infected gums is what owners usually notice first.
Daily brushing remains the gold standard. But realistically, most owners don’t brush their small dog’s teeth daily, which is why dental chews became a thing. The right chew, used consistently, meaningfully slows tartar buildup and keeps breath in check between professional cleanings.
A few hard truths first:
- No chew replaces actual dental cleaning. If your dog has visible tartar, gum redness, or persistent bad breath despite chews, they need a vet cleaning.
- The size of the chew matters. A chew swallowed in two bites doesn’t clean teeth — it just delivers calories.
- VOHC accreditation is the seal to look for. The Veterinary Oral Health Council independently tests products and only certifies ones that genuinely reduce plaque or tartar.
- Calories add up. Most dental chews are 50-90 calories each. For a 10 lb dog, that’s 15-25% of their daily calories. Reduce regular food on chew days.
What Makes a Good Dental Chew
Look for:
- VOHC seal — Veterinary Oral Health Council certification
- Right size for your dog’s weight — small/teenie versions for dogs under 25 lbs
- Texture that requires actual chewing — not soft enough to swallow whole
- Real ingredients with limited fillers and chemical preservatives
- Daily-use safe without causing GI upset
- Appropriate calories that don’t blow the daily allowance
What to skip:
- Rawhide — major choking and obstruction risk for small dogs
- Bones (cooked or raw) — can splinter or break teeth
- Hard nylon “indestructible” chews — too hard for small-dog teeth
- Pig ears, hoofs, antlers — common cause of fractured teeth in small breeds
- “Dental” treats without VOHC backing — many are just regular treats with marketing
Our 5 Picks
Greenies Original Teenie — Best Overall
The dental chew most vets recommend, and the most-bought small-dog chew on Amazon. Each chew is shaped to be flexible enough that small dogs can actually bite through it without breaking teeth, but firm enough that the chewing motion does real plaque scraping.
VOHC accredited for both plaque and tartar reduction. The Teenie size is for dogs 5-15 lbs — gives them about 30 seconds to a minute of chewing per piece, which is the sweet spot for cleaning. Available in original, fresh (mint), and other flavors.
What works: consistency. If you give one Greenie a day for a year, your dog’s tartar level will be visibly less than baseline. The texture genuinely cleans rather than crumbling.
What doesn’t: not for dogs with food allergies (contains wheat). Some dogs gulp them too fast, defeating the purpose — try the larger size if your dog inhales the Teenies. Also calorie-dense at ~26 calories per chew, so reduce regular food slightly on chew days.
Price: ~$24.99 (96 count, 27 oz)
OraVet Dental Hygiene Chews — Best for Plaque Prevention
Different mechanism than most dental chews. OraVet contains delmopinol, a compound that coats the teeth after chewing and creates a barrier that prevents bacteria from sticking. So the chew does immediate mechanical cleaning and leaves behind plaque-prevention coverage for hours.
VOHC accredited. Vets often recommend this specifically for dogs prone to plaque or with early gingivitis. The Extra Small (3.5-9 lbs) and Small (10-24 lbs) sizes are designed for small breeds.
What works: the dual mechanism — clean now, protect later — is genuinely different from “just chew and hope.” Dogs with chronic bad breath often see improvement within 2-3 weeks of daily use.
What doesn’t: more expensive per chew than Greenies. The proprietary delmopinol formulation isn’t suitable for dogs allergic to wheat (it’s wheat-based). Some dogs find them harder than other chews — for senior small dogs with weakened teeth, the Greenies texture is gentler.
Price: ~$23.99 (30 count, Extra Small)
Whimzees Variety Pack Small — Best Natural / Grain-Free
For owners who want a clean ingredient list. Whimzees are made from potato starch, glycerin, yeast, and natural plant-based ingredients — no wheat, no corn, no soy, no animal proteins. Vegetarian and grain-free, which makes them ideal for dogs with food sensitivities.
VOHC accredited. The variety pack rotates between Alligators, Brushzees, and Stix — different shapes that engage different parts of the mouth. The variety also keeps dogs more interested over weeks of daily use.
What works: clean ingredients, vegetarian-friendly, holds up to chewing without breaking teeth. The longer chew time (often 2-5 minutes per piece) means more thorough mechanical cleaning than fast-eaten Greenies.
What doesn’t: pricier per chew than Greenies. Some small dogs find the harder texture too much work and lose interest mid-chew. The Alligator and Brushzee shapes don’t fit every mouth comfortably — watch for which shapes your dog actually engages with.
Price: ~$19.99 (56 count Small)
Virbac C.E.T. VeggieDent FR3SH — Best for Bad Breath Specifically
The breath-focused option. VeggieDent FR3SH includes plant-derived antibacterial compounds (specifically from cardamom and pomegranate extract) that target the bacteria causing the foul-smelling sulfur compounds in dog breath. So it does general dental work plus active breath neutralizing.
VOHC accredited. Made by Virbac, a veterinary pharmaceutical company that also makes prescription dental care, so the manufacturing quality is well-regulated.
What works: noticeable breath improvement within days, not weeks. For dogs whose primary issue is bad breath rather than visible tartar, this is the most targeted option. Vegetarian and made with natural ingredients.
What doesn’t: harder to find at chain pet stores than Greenies — mostly online. The “Z” shape is sized for small dogs (10-30 lbs in the Small size) but very small breeds (under 10 lbs) may struggle. Pricier per chew, especially in the small-quantity packs.
Price: ~$22.99 (30 count Small)
Pedigree Dentastix Small — Best Budget Pick
The cheapest of the picks here, and the one to grab if you want to start a daily dental chew habit without spending much. Dentastix has its own chewy X-shape texture that scrapes plaque as the dog works through it. Available in flavors most dogs love (chicken, beef, fresh, bacon).
Not VOHC accredited at the time of writing, which is the main caveat — they’re effective for breath freshening and some plaque reduction, but the evidence is less rigorous than Greenies or OraVet. For dogs with mild dental concerns or as a daily habit-builder, fine. For dogs with serious dental disease, step up to a VOHC-certified option.
What works: cheap enough to give daily without thinking. Dogs love the taste. Made by Mars Petcare, so quality control is solid even at the budget tier.
What doesn’t: contains added flavors and preservatives that some owners want to avoid. The texture is on the softer side, so it doesn’t clean as deeply as a harder chew. Higher in carbs than ideal.
Price: ~$13.99 (small/medium pack)

How to Actually Use Them
A few rules that make any chew more effective:
Once a day, every day. Inconsistent chewing doesn’t work. Daily use is what shifts the plaque/tartar trajectory.
Adjust regular food. A 50-calorie chew is a meaningful chunk of a small dog’s daily calories. Reduce kibble portions on chew days to avoid weight gain.
Don’t chew while you’re not watching. Small dogs can break off and inhale chunks of any chew. Supervise the first few sessions with a new product to make sure your dog doesn’t gulp.
Swap occasionally. Some dogs lose interest in the same chew daily. Rotate between two products if engagement drops.
Combine with brushing if possible. Even brushing 2-3 times a week alongside daily chews dramatically extends time between professional cleanings.
Signs a Chew Isn’t Enough
Some patterns mean dental disease is past the point where chews can manage it:
- Visible yellow or brown tartar especially at the gum line
- Red, swollen, or bleeding gums
- Loose teeth or teeth that look like they’re moving
- Persistent bad breath despite consistent chew use
- Dog dropping food or chewing on one side only
- Pawing at the mouth or face rubbing
For these, a vet exam and likely a professional cleaning under anesthesia is needed. Once you reset to clean teeth, daily chews keep them that way much more effectively.
Special Considerations for Toy and Teacup Breeds
For very small dogs (under 10 lbs):
- Teenie size or smaller only — Standard dental chews can fracture tiny teeth
- Watch chew time — toy breeds tire faster; you may need to break the chew in half
- Soft tissue around teeth is fragile — don’t force a chew session if the dog isn’t engaged
- Teacup-specific options exist — OraVet Extra Small is sized for 3.5-9 lb dogs
Toy breeds also need professional cleanings more frequently than larger dogs (often annually starting at age 3-4).
FAQ
How often should I give my dog a dental chew? Once a day is the recommended frequency for VOHC-certified chews. More than that adds calories without proportional dental benefit.
Are dental chews safe for puppies? Most are labeled for dogs 6 months and older. Puppy teeth are too fragile for hard chews; the soft Greenies puppy line is appropriate from 6+ months.
Can my dog eat dental chews if they have a sensitive stomach? Whimzees (vegetarian, no animal proteins) is usually the best-tolerated. Avoid wheat-based chews if your dog has known wheat sensitivity.
Do dental chews replace brushing? No, but they’re a meaningful supplement. Brushing reaches surfaces chews don’t (the inside of teeth, the gum line). Daily chew + 3x weekly brushing is realistic and effective for most owners.
Why does my dog’s breath still smell bad after using chews for a month? Two possibilities: (1) the underlying tartar is past what chews can fix and your dog needs a professional cleaning, or (2) the bad breath is coming from something other than dental disease — kidney disease, GI issues, or oral tumors. See a vet.
