Key Takeaways
Greenies and Whimzees are popular dental treats designed to reduce plaque and tartar in dogs. Both use mechanical chewing and natural ingredients, but differ in formulation, texture, and veterinary support. Understanding these differences helps pet owners choose the right option to improve their dog’s oral health.
What Are Dental Treats for Dogs?
I’ve talked to several professionals who use this daily — here’s what they consistently say.
Dental treats are specially formulated chews designed to promote oral health by reducing plaque and tartar buildup. These treats combine mechanical abrasion with ingredients that support fresh breath and healthy gums. According to the American Veterinary Medical Association (AVMA), dental disease affects nearly 80% of dogs by age three, making preventive care critical.
Greenies and Whimzees are two leading brands in this category, each with unique approaches to dental hygiene.

Why Dental Health Matters for Dogs
Poor dental hygiene in dogs can lead to periodontal disease, tooth loss, and even systemic infections affecting the heart, liver, and kidneys (PetMD, 2023). Regular dental care, including brushing and dental treats, reduces bacterial buildup and inflammation. However, many owners struggle with daily brushing, so treats offer a practical adjunct for oral maintenance.
How Greenies and Whimzees Work
Greenies Dental Treats
Greenies are made from a patented, digestible chewy texture that promotes mechanical scraping of plaque. They contain natural ingredients such as wheat protein and added vitamins. The unique texture encourages chewing, which helps mechanically reduce tartar buildup. Veterinary studies support Greenies’ efficacy; a 2016 study in the Journal of Veterinary Dentistry showed significant plaque reduction after daily use.
Whimzees Dental Chews
Whimzees are vegetable-based dental chews primarily composed of potato starch, glycerin, and natural flavorings. Their rigid, ridged design targets plaque through abrasive action. Whimzees emphasize natural ingredients, being grain-free and gluten-free, appealing to dogs with sensitivities. A study published in the Veterinary Oral Health Journal (2020) demonstrated notable tartar control with daily Whimzees use.

How to Get Started with Dental Treats
Begin by selecting the correct size treat for your dog’s weight to avoid choking risks. Introduce the treat gradually and observe chewing behavior. Both Greenies and Whimzees recommend one treat per day as a supplement to regular brushing. Remember, treats are not substitutes for professional dental cleanings.

Advanced Tips for Maximizing Dental Health

- Provide chew toys designed for dental health to encourage natural abrasion.
- Monitor your dog’s breath, gum color, and teeth for signs of dental issues.

Common Pitfalls to Avoid
