Popular Dog Dental Chews: BARK Bright vs. Greenies vs. Dentastix vs. Whimzees

Written by: Elise Remp

February 10, 2022

You know you’re supposed to be brushing your dogs teeth daily (though only 2% of pup parents do!), but your dog has been fighting you tooth and nail just to get a toothbrush anywhere near their mouth. And you wonder, with your fingers covered in canine saliva and the emotional state of a soldier defeated in battle, whether perhaps dental chews are enough.

Thing is, there are a ridiculous number of dental chews to choose from, no matter where you search. So which ones work best?

We broke down the major differences between some of the most popular big brand dental chews, Greenies, Pedigree Dentastix, and Whimzees, alongside BARK Bright’s own toothbrush-free dental system.

What Are Dental Chews?

Dental chews are the ideal solution for a lot of dog parents who just can’t seem to win the battle when it comes to brushing their dog’s teeth. Giving your pup routine dental chew treats can help control plaque build up and prevent gingivitis, inflammation, bad breath, tooth decay, and even heart disease that can result from oral health neglect.

But all dental chews are not created equal. Below we’ll break down the key differences between some of the most popular dog dental chews out there: BARK Bright, Greenies, Dentastix and Whimzees.

Dental Chew Contenders

Understanding what dental chews can and can’t do for your dog’s teeth and breath is important when deciding how to choose the best option for their overall health.

1. BARK Bright Dental Kit

BARK Bright is the first and only daily dual toothpaste and dental chew system that helps remove plaque and debris buildup, as well as keep your pup’s breath fresh for all the kisses you can handle! The secret is in the triple-enzymatic toothpaste you put IN the chew itself—it has 3 enzymes that work to break down plaque and nasty bad breath-causing bacteria. (More about this below!)

Dental chews alone can aid in scrubbing away food debris that forms plaque, but giving your dog dental chews alone is like brushing your teeth with a toothbrush but no toothpaste. It’s a start, but you can do better! A dental chew is a great first step, but the BARK Bright system helps your pup level up.

BARK Bright dental chews and toothpaste are available as a subscription (so you never run out!), or individually at several retail locations like Target, Petco, PetSmart, and CVS. Each dental kit includes a month’s supply of daily dental chews and a tube of triple-enzymatic toothpaste.

2. Greenies Original

Greenies’ soft and flexible texture allows dogs to chew and sink their teeth in. This helps scrape away the smelly debris (like leftover food) and plaque, similar to the scrubby action of a toothbrush. But to your dog, they’re just a tasty, easily digestible treat with natural ingredients that help freshen their breath. Greenies also offers a grain-free option.

Greenies offers a monthly subscription service for their dental chews as well as one-time purchase packs, and they even help you find the right chews for your pup by answering a few quick questions about their health. Other variations in their dental treat line include chews for weight management, aging care, and puppies.

Note: Not suitable for dogs younger than 6 months or under 5lbs, due to texture.

3. Dentastix Original

Dentastix chewy texture helps reduce plaque buildup to freshen breath, and their X-shaped chews claim to clean down to the gumline, where bacteria thrive. Dentastix do not contain any added sugars or fillers.

Note: Not suitable for dogs under 22lbs, due to texture.

4. Whimzees

Whimzees are that they are grain-free, vegetarian, gluten-free and offer a few different fun shapes (like an alligator or hedgehog, among others). Similarly to the other brands discussed, these chews help improve your dog’s dental health by scraping away plaque and leftover food debris as your pup chews, but Whimzees also claims to last 3 times longer than leading brands.

Manufactured in the Netherlands, Whimzees also strives for sustainability by reusing energy during the manufacturing process, sourcing ingredients locally, reducing their carbon footprint with zero water waste, and composting other waste from manufacturing. You can read more about their efforts here.

Note: Not suitable for dogs younger than 9 months or weighing fewer than 5lbs due to firm texture.

Dental Chew Effectiveness (How They Work)

Prepare for incoming kisses! See how these dental chews really get down to business.

1. BARK Bright Dental Kit

  • The chews’ chewy texture and unique star shape help remove plaque down to the gumline as your dog chews.
  • Toothpaste enzyme #1 (Amyloglucosidase, or AMG) breaks down starches and complex sugars from food debris into glucose.
  • Toothpaste enzyme #2 (Glucose oxidase, or GOX) turns that glucose into a safe and effective natural cleaning agent to scrub away bacteria.
  • Toothpaste enzyme #3 (Lactoperoxidase) helps boost the performance of bacteria removal to give your pup fresher breath. (Note: These enzymes continue to work even after your dog has scarfed down the dental chew.)

2. Greenies Original

  • Flexible, chewy texture and toothbrush bristle-shaped grooves help reduce plaque buildup down to the gumline as your dog chews.

3. Dentastix Original

  • Chewy texture and X-shaped chews help remove plaque buildup from teeth and gumline as your dog chews.

4. Whimzees

  • Unique shapes and firm texture mechanically remove plaque buildup as your dog chews for an extended time.

Dental Chew Calorie Count

Dental care is an essential component of dogs’ overall wellbeing, but daily chews shouldn’t be given at the expense of their ideal weight. Your vet can give you an idea of your dog’s current body condition, and how many calories they should be able to consume in treats on a daily basis (treats shouldn’t make up more than around 10% of dogs’ overall daily calorie intake).
