Dog soap for sensitive skin

Difficulty: Beginners
Time: 30 mins
Yields: 6 small soaps

Skin pH is a tricky thing. And while certain ingredients used in soaps and shampoos might be great for our skin and hair, it doesn’t mean it’s also good for our canine friends and can cause itching, flakiness and be generally irritating to a dog.

Human skin has a pH level on the acidic side, around 5.5, which helps us combat germs and infection on our skin. Dogs, however, have a much more neutral skin pH, between 6.5 and 8, which is why it so important to use the right products for dogs as not to irritate their skin.

I always test a soap or any product that is designated for use on dogs. Since soaps have a tendency to be slightly more alkaline, a good trick is to add citric acid. One teaspoon of citric acid to 1000 g of soap can bring the pH down approximately by 0.5. So you don’t need much.

This recipe is formulated especially for our fur babies with sensitive skin, and contains shea butter, colloidal oatmeal and castor oil, which will help balance and soothe the skin.


ONE: Cut the soap into small cubes and add them to a heat proof Pyrex jug. Heat on high in the microwave in 20 second bursts, until the soap has melted. Try to avoid the soap from reaching boiling point!

I am using shea butter melt and pour soap base, from Pure Nature, because shea butter is great for dry and sensitive skins and helps balance and nourish the skin. Alternatively, you can also use the triple butter soap base, which is more nourishing, or the SLS-free soap base, for very sensitive skins.

TWO: Mix together two teaspoons of colloidal oatmeal, 1/4 teaspoon of citric acid and 1 teaspoon of castor oil, and then add the mixture to the soap. (In the picture I added the oatmeal directly to the soap, and as you can see it has formed clumps, which despite whisking furiously, I couldn’t make disappear). Oatmeal has been used throughout time to soothe dry, irritated and inflamed skin. In addition, it is also full of skin-loving vitamins and minerals, which help nourish the skin. I’m also adding castor oil, which is also known to help restore skin’s moisture balance and helps promote a healthy, shiny coat. And the citric acid will bring down the pH of the soap.


FOUR: Give everything a good stir to ensure everything is well dispersed throughout the soap and then pour it into your mold. I’m using little paw molds that I found on AliExpress. Leave the soaps to harden for a few hours before unmolding. Make sure you package these soaps into little cello bags or glad wrap, because these melt and pour soap bases attract humidity and little beads of moisture will form on the surface if not properly packaged.

PS if you like this cool dog paw mould, I got it from AliExpress 😉

    • When you use ready made soap bases, like this melt and pour soap, any extra oils added will only seep out. So unfortunately, you can’t add it to the soap. Sorry!

  1. STOP!!! PLEASE LISTEN! Peppermint and lemongrass are toxic to dogs!
    I make these bars for a dog groomer friend of mine (minus those two ingredients) and she LOVES them.
    So PLEASE change the recipe before someone’s fur friend gets hurt!
