If you happened upon this article from a Google search, you probably saw there’s quite a bit of debate across the Internet: is it okay to use baking soda (sodium bicarbonate) to brush your dog’s teeth?

When it comes to your dog’s health and safety, inconclusive and confusing answers just don’t cut it, so we got our paws dirty to dig into the details and find the answers.

Is Baking Soda Safe For Dogs?

The short answer: It depends. Although small amounts of baking soda can be relatively harmless, it can cause upset stomachs and research has shown that larger amounts can even be toxic to dogs1.

The long answer: Baking soda is really best avoided as an ingredient in dog toothpaste, for a couple important reasons. One, it can be irritating to your pup’s stomach if ingested, even in small amounts, since dogs can’t really spit out their toothpaste like we can. Two, it doesn’t have the most appetizing taste1, which may make brushing your dog’s teeth even more of a chore.

And even worse, baking soda is toxic to dogs in large amounts2! If your dog ends up swallowing too much while brushing their teeth, or even gets ahold of the container of baking soda itself, that could be a recipe for disaster.

Signs Of Baking Soda Toxicity:

  • Diarrhea
  • Vomiting
  • Depression
  • Lethargy
  • Tremors
  • Seizures
  • Shortness of breath
  • Disorientation

How Much Baking Soda Is Toxic To My Dog?

Toxicity from baking soda occurs when your dog ingests 10–20 grams of baking soda per kilogram of body weight. In English units, that’s 5–11 teaspoons per pound of your pup’s body weight2.

What Is A Good Alternative To Baking Soda For Dog Toothpaste?

Baking soda is usually used in toothpastes for its abrasive qualities that help clean the surface of the teeth. It’s also helpful as a deodorizer for any stanky doggy breath2. But in the wide world of ingredients and brushing methods, there are just far better and safer alternatives out there when it comes to the health of your pup.


If you’re already brushing your dog’s teeth, chances are that you’re using a toothbrush or finger brush along with a dog-friendly toothpaste. The brush itself takes the lead with abrasive scrubbing action to clean the surface of your pup’s teeth (but remember to be gentle! Hard brushing is not more effective than gentle brushing, and can actually hurt your dog).

Brushing in and of itself is the most effective part of the tooth-brushing process for dog dental health. Doggie toothpastes may include additional ingredients to give the dental cleaning a boost (from enzymes to chelators that help prevent the hard stuff from forming on the teeth), and they also make tooth-brushing a fun/yummy experience that your dog will want to repeat on the daily.


You’re going to be hard pressed to find a homemade toothpaste ingredient that’s entirely safe for dog consumption if you’re looking to help deodorize that funky dog breath.

The biggest difference between brushing a human’s teeth and brushing a dog’s teeth is that they can’t spit anything out when they’re done. It’s really best to leave it up to the pros.

What Other Ingredients Should I Avoid In Dog Toothpaste?

Most importantly, never use human toothpaste for your dog. Our toothpastes often contain ingredients that can be harmful to your pup. But even some toothpastes made specifically for dogs can include ingredients that should be avoided. These include:

Dog Toothpaste Ingredients To Avoid:

  • Xylitol (birch sugar)
  • Fluoride
  • Baking Soda (sodium bicarbonate)
  • Detergents
  • Salt
