Is Baking Soda Harmful to Dog’s Skin?

Baking soda is completely safe for dogs and can be applied to their skin for various reasons. For example, baking soda is an ingredient of many dog shampoos because it acts as a deodorizer. Similarly, it is used for treating dryness, itching, and skin inflammation. This is because it has anti-bacterial and anti-inflammatory properties and will improve your pup’s fur.

However, it is not recommended to sprinkle baking soda directly on your dog’s coat. Instead, you can make a spray and apply it to the inflamed parts of the body. One of the ways to make this natural spray is as follows.

Yes, you can and it will be quite effective if you have followed the right method. Baking soda is a very efficient dehydrating agent and will kill fleas by draining the moisture from their bodies. It can also rehydrate flea eggs and larvae to ensure that a re-infestation won’t happen.

However, you may need to combine it with some other ingredients, like salt and apple cider vinegar. Both these household commodities will make baking soda even more potent. You can also add some water to this mixture for diluting the acid of the vinegar.

Fleas don’t like the scent and taste of apple cider vinegar and will try to leave your dog’s body. On the other hand, the grains of salt can go deep into your dog’s skin and will pull more fleas out. Therefore, it is often recommended to use this solution to get rid of fleas on dogs.

Otherwise, excessive bathing can worsen the situation because it leads to dry skin and other skin problems. All the ingredients used in this recipe are natural and will yield good results when used properly.


  • ¼ cup baking soda
  • 1 tablespoon of apple cider vinegar
  • 5 drops of peppermint oil
  • 2 cups of warm water


  1. Pour the water into a bowl and add baking soda and apple cider vinegar to it.
  2. Then, add the peppermint oil to make the solution even more irritating for fleas.
  3. Rub this mixture into the fur (avoiding his face).
  4. Brush or comb through your pooch’s fur, getting the ingredients down to his skin.
  5. Leave on for at least five minutes, longer if your doggie is happy to allow you.
  6. Leave the mixture on your dog, just give him a rub down with a dry towel to get off any excess moisture, and repeat once a week.
  7. You can also use this concoction as a final rinse if you have used a commercial dog shampoo. Since baking soda is alkaline, it will neutralize any acids contained in the shampoo, restoring the ph balance of his skin and will effectively get rid of your doggie’s fleas.
