Key Points

  • The #1 Best Overall oatmeal dog shampoo is Earthbath Oatmeal & Aloe Fragrance Free Dog & Cat Shampoo.
  • Some of the best dog shampoos on the market include colloidal oatmeal in the ingredients, which has antioxidant and inflammatory properties to help combat dryness, irritation, and flaking in your dog’s skin.
  • When considering what kind of shampoo to buy for your dog, you should consider their skin condition, any allergies or sensitivities they have, and convenience — whether a traditional shampoo would work best, or if you’d prefer to use a shampoo bar.
  • A dog’s pH level is more neutral than a human’s, so the shampoo used on it must match it’s pH level. If you use human shampoo on a dog, it may upset the pH balance of their skin, leading to skin issues.

When it’s time to wash your dog, you may be tempted to use your shampoo. While your hair care products make your tresses look fabulous, they may actually irritate your pup’s skin. That’s because the potential hydrogen (pH) level of human skin is very different from dog skin.

In skincare, pH refers to the skin’s acidity level. A dog’s pH level is more neutral than a human’s, which is why using your shampoo on your pup may upset the pH balance of their skin, causing dryness, irritation, and flaking.  

The best way to ensure that bathing your dog doesn’t cause skin problems is to use a dog shampoo that is formulated to match a dog’s pH level. Some of the best dog shampoos include colloidal oatmeal, a natural ingredient made by grinding oats into a fine powder. Colloidal oatmeal has antioxidant and anti-inflammatory properties that will keep your dog’s skin healthy and hydrated.

How to Choose the Right Oatmeal Shampoo for Your Dog

There are three main factors to consider when selecting the right oatmeal shampoo for your dog:

  • Skin condition
  • Allergies and sensitivities
  • Convenience

Let’s examine these factors in detail.

Skin Condition

If your dog is prone to dry, itchy, irritated skin, an oatmeal shampoo will facilitate healing and maintain healthy skin. Other natural ingredients, such as honey and vitamin E, can also help promote healing. Also look for products that include a ceramide complex, which will lock moisture into your furry pal’s skin and help to protect her epidermis (outer layer of skin) from environmental damage.

Allergies and Sensitivities

It’s important to select a dog shampoo that doesn’t contain ingredients that will aggravate your pet’s allergies or sensitivities. When purchasing a dog shampoo online, read the ingredients carefully for potential allergens. Remember that companies sometimes change ingredients. So, when you receive the shampoo, read the label again to ensure that the formula didn’t change.

If your dog is sensitive to fragrance, be sure to select a shampoo that’s fragrance-free.

Convenience

Do you find opening a shampoo bottle and pouring its contents into your hand while trying to handle a wet dog to be difficult? If so, a dog shampoo bar may be just the solution that you’ve been looking for. Shampoo bars are easy to handle with one hand so you can keep your pup safely under control with the other.  

Our Criteria and Experience: How We Chose the Best

When creating our list of the best oatmeal dog shampoos, we researched various ones on the market, consulted tests and reviews of the products, and narrowed down our choices to the four best. Here are some further details we wanted to share about the items:

  • When it comes to any kind of product that comes into contact with skin, be it for dogs or humans, there should be some kind of guarantee in case there is an allergic reaction to a product. We love that our overall pick has a 100% money back guarantee on the product so, on the off-chance your dog can’t tolerate this particular shampoo, you won’t lose any money.
  • Our #2 Burt’s Bees product is very popular with customers who used it and, as we should all know, it’s a high-caliber brand all around when it comes to creating quality, safe products. Some reviewers found that this shampoo healed up their senior dogs’ skin when other similar, more expensive products did not deliver.
  • The #3 shampoo on our list is vet recommended. It works well even on dogs with thick, tough coats, softening their hair nicely. It does well for dogs that are highly allergic, and you can even use it on their paws after taking walks, as dogs can pick up airborne allergies in their paws.
  • We find that the #4 Wondercide shampoo bar lathers very easily, is ultra-gentle on the skin of short-haired dogs, and reduces scratching from flea issues.

The 4 Best Oatmeal Dog Shampoos: Reviewed and Ranked FAQs (Frequently Asked Questions) 

What’s so great about colloidal oatmeal?

Humans have used colloidal oatmeal for centuries. They used it to treat a wide variety of skin conditions, including dryness, redness, itchiness, and eczema. Now we understand the science behind this powerful natural ingredient, and we know that dogs can also benefit from its soothing and healing properties.

The right dog shampoo containing colloidal oatmeal can help calm and heal your pet’s irritated, itchy skin. With continued use, it will help to maintain healthy skin and a soft, shiny coat.

How often can I bathe my dog with oatmeal shampoo?

If your dog has healthy skin, you can bathe her once a month. More frequent baths can dry out her skin. If your pet currently has a skin condition, you may bathe her with oatmeal shampoo once or twice a week if your veterinarian advises you to do so.

Is oatmeal dog shampoo good for itchy skin?

Yes. Whether your dog’s skin is irritated from allergies, sensitivities, or insect bites, oatmeal dog shampoo can help relieve and heal her dry, itchy skin.
