Greenies vs Whimzees vs Crumps Naturals Dental Chews for Dogs Canada 2026: Which Cleans Teeth Best?

Dental disease affects over 80% of dogs by age three, according to the American Veterinary Medical Association (AVMA) — making daily dental hygiene one of the most overlooked but critical parts of pet care. Dental chews are a convenient, treat-based way to help reduce plaque and tartar buildup between professional cleanings. In Canada, three brands consistently top pet owners' shopping lists: Greenies, Whimzees, and Crumps' Naturals. This 2026 comparison breaks down exactly how they differ so you can choose the right one for your dog. Browse our full dog treats collection at Ashario Pets to see what's currently in stock.

Our team at Ashario Pets' North York store on Finch Ave gets asked almost daily: "Which dental chew actually works?" The answer isn't one-size-fits-all. It depends on your dog's size, chew style, ingredient sensitivities, and whether you're prioritizing mechanical scrubbing action, low-calorie snacking, or a Canadian-made, minimal-ingredient option. Let's dig in.

Why Dog Dental Chews Matter: The Science Behind Clean Teeth

Daily dental chewing reduces plaque accumulation by up to 69% and tartar by up to 43%, based on studies cited by the National Center for Biotechnology Information (NCBI/PubMed) on mechanical abrasion in companion animals. Dental chews work through two primary mechanisms: physical abrasion as the dog chews through the product's texture, and in some cases, active ingredients like sodium hexametaphosphate that chemically inhibit tartar mineralization.

The Veterinary Oral Health Council (VOHC) Seal of Acceptance is the gold standard marker for dental efficacy. Products bearing this seal have passed controlled clinical trials demonstrating measurable plaque or tartar reduction. As of 2026, Greenies carries the VOHC seal — a meaningful differentiator in this comparison. When a customer comes in asking which dental chew is worth the money, we always ask whether their vet has flagged periodontal concerns, because that changes the priority considerably.

Key Takeaway: Dental chews aren't a replacement for professional veterinary dental cleanings, but consistent daily use of a quality chew can meaningfully slow plaque and tartar accumulation. Always consult your veterinarian if your dog shows signs of gum disease, bad breath that persists, or tooth pain.

Greenies Dental Chews: The Clinically Backed Classic

Greenies are the most widely recognized dental chew brand in North America, carrying the VOHC Seal for both plaque and tartar reduction. They contain approximately 30% protein content, 5.5% fat content, and 2.5% fiber content per regular-size chew, with roughly 54 kcal per regular treat. The primary active ingredient is highly soluble wheat protein that creates a chewy, toothbrush-like texture that bends and flexes around each tooth surface as the dog chews.

Greenies are available in a wide size range — Teenie (for dogs 5–15 lbs), Petite (15–25 lbs), Regular (25–50 lbs), Large (50–100 lbs), and Jumbo (over 100 lbs) — making them accessible for virtually every dog. Their formula is AAFCO-compliant as a supplemental treat and uses natural ingredients with added vitamins and minerals. The texture is intentionally soft enough to be digestible yet firm enough for mechanical cleaning action.

One consideration: Greenies contain wheat, making them unsuitable for dogs on grain-free or limited ingredient diets. Pet owners tell us their dogs absolutely love the flavour — chicken and original are the most requested at our store — but dogs with wheat sensitivities or diagnosed grain intolerances should look at the alternatives below. You can shop Greenies dental chews at Ashario Pets in-store or online.

Whimzees Dental Chews: The Grain-Free, Vegetable-Based Alternative

Whimzees are a standout option for dogs who need grain-free dental treats with a short, clean ingredient list. Made in the Netherlands with only six or fewer natural ingredients — including potato starch, glycerin, powdered cellulose, and lecithin — Whimzees contain no artificial colours, flavours, or preservatives, and no gluten, meat, or animal by-products. This makes them a strong choice for dogs with poultry or meat sensitivities who still need daily dental support.

Whimzees also carry the VOHC Seal of Acceptance, confirming clinical efficacy for tartar reduction. Their protein content is lower than Greenies at approximately 6%, reflecting their plant-based composition, while their fiber content sits around 14% — notably higher, which contributes to longer chew time and extended mechanical contact with tooth surfaces. A Whimzees Regular chew delivers approximately 90 kcal, making calorie tracking important for smaller dogs.

The brand's signature shapes — Alligator, Toothbrush, Hedgehog, and Stix — aren't just cosmetic. Each shape is engineered to create different chewing angles that target different tooth zones. The elongated ridges on the Toothbrush shape, for example, are designed to reach the back molars where tartar most commonly accumulates. In our store, we see customers with dogs on limited ingredient diets gravitate toward Whimzees as their go-to dental solution. Their fully vegetarian composition is also popular among owners who prefer plant-forward diets for ethical reasons.

Crumps' Naturals Dental Sticks: The Canadian-Made Minimalist Option

Crumps' Naturals is a proudly Canadian brand and one of our most beloved homegrown labels at Ashario Pets. Their Dental Sticks are made in Canada with a short ingredient list, typically featuring sweet potato, tapioca, and other whole-food ingredients depending on the variety. They're free from wheat, corn, soy, and artificial additives — making them a genuinely clean-label dental chew that aligns with a natural feeding philosophy.

From a nutritional standpoint, Crumps' Naturals Dental Sticks run approximately 8–10% protein, 1.5% fat, and 3% fiber, with roughly 20–35 kcal per stick depending on size. They're lighter in calories than either Greenies or Whimzees, which matters significantly for small breeds or dogs managing their weight. The semi-firm texture provides solid abrasive action, though the chew time tends to be shorter than Whimzees for enthusiastic chewers.

The primary difference here is certification: as of 2026, Crumps' Naturals Dental Sticks do not carry the VOHC Seal, which means their dental efficacy hasn't been validated through the same controlled clinical trial process as Greenies and Whimzees. That said, their mechanical abrasion and clean-ingredient profile make them a strong daily-use option, especially for dogs whose owners prioritize supporting Canadian-made, natural pet products. Our nutrition experts at the North York store often recommend Crumps' Naturals for dogs who do well on single-protein, whole-food treats and whose owners want to minimize processed additives.

Which Dental Chew Is Right for Your Dog?

Choosing between these three comes down to four practical questions: Does your dog have ingredient sensitivities? Does your vet prioritize clinical efficacy above all else? Are calories a concern? And does supporting Canadian manufacturing matter to your family?

Choose Greenies if your dog has no grain sensitivities, your vet has flagged dental disease as a concern, and you want the most rigorously tested product on the market. The VOHC dual-seal for both plaque and tartar, combined with wide size availability, makes Greenies the most versatile clinical option.

Choose Whimzees if your dog is on a grain-free or limited ingredient diet, or if you have a dog with poultry or meat protein sensitivities. The high fiber content means longer chew times — ideal for power chewers — and the VOHC certification means you're not sacrificing efficacy for a clean label.

Choose Crumps' Naturals if you're committed to natural, Canadian-made products with whole-food ingredients and want a lighter-calorie daily option. They're particularly well-suited to small breeds, senior dogs, or dogs managing their weight. While they lack the VOHC seal, their abrasive texture and clean ingredients make them a respectable daily-use treat. Browse dog health and wellness products at Ashario Pets to complement your dog's dental care routine with supplements and other wellness essentials.

In our store, we see customers often use a combination approach: Greenies or Whimzees for days when dental attention is the priority, and Crumps' Naturals as an everyday reward treat that still contributes to oral hygiene. This hybrid strategy keeps things interesting for the dog and flexible for the owner's budget and feeding philosophy.

Frequently Asked Questions: Dog Dental Chews in Canada 2026

Are Greenies or Whimzees better for dogs with grain sensitivities in Canada?

Whimzees are the better choice for dogs with grain sensitivities because they are entirely grain-free, made from potato starch, glycerin, and powdered cellulose with no wheat, corn, or soy. Greenies contain wheat protein as a primary ingredient and are not suitable for dogs with grain intolerance or wheat allergies. Both carry the VOHC Seal for tartar reduction, so grain-sensitive dogs don't have to sacrifice clinical efficacy by choosing Whimzees.

Does Crumps' Naturals have the VOHC seal for dental efficacy?

As of 2026, Crumps' Naturals Dental Sticks do not carry the VOHC (Veterinary Oral Health Council) Seal of Acceptance. This means their dental cleaning claims have not been validated through the same controlled clinical trials as Greenies or Whimzees. However, their firm, abrasive texture does provide mechanical plaque reduction through chewing action, and their clean Canadian-made ingredient list makes them a popular natural alternative for owners who prioritize whole-food formulations.

How many calories are in a Whimzees vs a Greenies dental chew?

A regular-size Whimzees chew contains approximately 90 kcal, while a regular-size Greenies chew contains approximately 54 kcal. A Crumps' Naturals Dental Stick is the lightest at roughly 20–35 kcal depending on the size variant. For calorie-conscious owners or dogs on a weight management plan, these differences are meaningful — especially if dental chews are given daily. Always factor treat calories into your dog's total daily kcal intake, following your veterinarian's feeding guidelines.

Can I use dental chews as the only form of dental care for my dog?

Dental chews should be used as part of a broader oral hygiene routine, not as the sole method of dental care. The AVMA recommends daily tooth brushing as the gold standard for canine dental health, supplemented by dental chews, dental diets, and regular professional veterinary cleanings. Dental chews meaningfully reduce plaque and tartar accumulation between brushings, but they cannot replace a veterinary dental examination or address existing periodontal disease. If your dog has persistent bad breath, visible tartar, or signs of gum inflammation, consult your veterinarian promptly.
