What’s in it
The entire ingredient panel: Potato Starch, Glycerin, Powdered Cellulose, Lecithin, Dried Yeast, Malt Extract, Sweet Lupin Meal, Alfalfa Extract, Paprika Extract. That’s it — nine ingredients, all plant-derived, no animal protein. Each Medium Stix is approximately 87 kcal. The product carries the AAFCO “intermittent or supplemental feeding only” statement.
Whimzees is a Netherlands-based brand (now owned by WellPet, same parent as Wellness Soft WellBites) that’s built its positioning entirely on plant-based, grain-free, additive-free dental chews. The texture is rigid and ridged to provide mechanical abrasion on tooth surfaces as the dog chews, which is the core functional claim.
Sizing: Whimzees publishes four Stix sizes matched to dog weight — XS (5–15 lbs, 22 kcal), S (15–25 lbs, 44 kcal), M (25–40 lbs, 87 kcal), L (40–60 lbs, 174 kcal). Our rubric rewards size-tiered dental chews +2 for matching chew size to dog weight.
The good stuff
The ingredient panel is notably clean for the dental-chew category. No wheat, no corn, no soy, no rice. No BHA, no BHT, no ethoxyquin, no artificial colors, no artificial flavors. Compare to the typical mainstream dental chew, which leads with wheat flour, adds glycerin + wheat gluten, and preserves with BHA or similar — Whimzees avoids every one of those rubric deductions.

Powdered cellulose at position three is the functional mechanical-dental ingredient. Cellulose provides abrasive surface structure during chewing, which is the primary way dental chews work (gentle scrubbing action on tooth enamel). It’s also a soluble fiber that supports GI transit. The rubric doesn’t specifically bonus cellulose, but it’s functionally load-bearing for the dental-claim.
Lecithin and sweet lupin meal bring plant-based amino acids and choline. Lecithin supports coat health and brain function; lupin is a high-protein legume relative that’s hypoallergenic and rare in US-formulated treats. Alfalfa extract and paprika extract provide natural coloring (no artificial colors needed) plus minor vitamin/mineral content.
Size-tiered sizing is a meaningful rubric advantage. Dental chews that come in only one size can’t be correctly dosed for a chihuahua vs. a golden retriever; Whimzees’s four-size lineup means the dental action matches the dog’s mouth mechanics. Our rubric awards +2 for this.
There are no active FDA recalls or enforcement actions on Whimzees Stix product line as of this review’s verification date.
The not-so-good stuff
No VOHC Seal on the Stix shape. The Veterinary Oral Health Council (VOHC) only awards its seal to products that complete specific plaque-and-tartar efficacy trials at specific dosing frequencies; Whimzees has earned the seal for some of its other shapes (notably Toothbrush and Alligator) but not for Stix. This is the single biggest rubric gap between Whimzees Stix and Greenies Original Regular, which does carry VOHC acceptance. Our rubric gives VOHC-accepted dental chews a stacked +3 function-class bonus (total +6 for VOHC dental chews) that non-VOHC dental chews don’t receive (only +1). The efficacy claim here is based on generalized plant-based mechanical action, not on Stix-specific clinical evidence.
Potato starch at position one. Our rubric deducts 8 points for a starch-first ingredient in a non-biscuit, non-dental-chew class; Whimzees is classified as dental-chew so the deduction is softer (−3), but starch-first is still not ideal. This is essentially a structural ingredient that does the chew-structure job without nutritional contribution.
Glycerin at position two. Glycerin is the plasticizer that lets Whimzees maintain its ridged texture without cracking. Our rubric deducts 5 points for glycerin as a softener. This is an unavoidable formulation choice for the rigid-but-chewable dental-chew texture.
High calorie density per chew. Medium Stix is 87 kcal, which is about 79% of a 50-pound dog’s entire 110-kcal daily treat budget. This is correct for a once-daily dental chew positioning, but it means you cannot stack Whimzees on top of a full day of training treats without blowing past the 10% ceiling. Large Stix (174 kcal) exceeds the treat budget for any dog under 80 pounds, so size matters.
No animal protein in the panel. If your dog eats Whimzees strictly as a dental-function chew, this is fine. If you’re using it as a general reward or chew, the plant-based panel may not be motivating enough — pair with a meat-first primary diet.
How it compares
Against Greenies Original Regular (C/58), Whimzees Stix wins on ingredient-panel cleanliness (no wheat flour, no wheat gluten, no artificial color) but loses on VOHC-verification. For dog-parents whose primary concern is documented dental efficacy, Greenies is the right call. For dog-parents whose primary concern is ingredient transparency and simplicity, Whimzees is the right call. Both are C-B range treats with complementary strengths.
Against training-treats — PureBites (B/81), Zuke’s (B/78), Wellness WellBites (B/78) — Whimzees is a different product category. Training treats are multi-piece-per-session, high-volume, low-calorie-per-piece. Whimzees is one-chew-per-day, high-calorie-per-chew, mechanical-dental-purpose. Don’t substitute them for each other.
Against A-tier freeze-dried options — Vital Essentials (A/93), Charlee Bear (A/90), Stella & Chewy’s Carnivore Crunch (A/92) — Whimzees falls short on panel protein content, which is expected for a plant-based dental-chew. The categories are solving different jobs.
The bottom line
Whimzees Stix earns a B grade (76/100) on KibbleIQ’s treats rubric — the cleanest plant-based dental chew on the mainstream shelf, with four correctly-sized SKUs and a panel that avoids every mainstream dental-chew shortcut. Size to your dog’s weight (don’t feed Medium to a 60-lb dog, don’t feed Large to a 30-lb dog) and treat this as a once-daily positional chew rather than a high-volume treat. If VOHC-verified mechanical-dental-cleaning is the primary decision factor, Greenies Original Regular (C/58) has the seal that the Stix shape doesn’t. If ingredient transparency matters more, Whimzees is the stronger pick. See our Treats Rubric methodology for the full scoring logic. Shop on Amazon →
