What is Hypoallergenic Dog Shampoo?

What is hypoallergenic dog shampoo?

It may surprise you to learn that there are no specific national standards or regulations in the United States that define or regulate the term "hypoallergenic" for pet products, including hypoallergenic dog shampoos.

This lack of standardized regulation means that the use of the term "hypoallergenic" on pet product labels can vary significantly between manufacturers.

I've seen many so called natural pet shampoos that are labeled as hypoallergenic but when I look at the ingredients I see ingredients that are linked to skin irritation or allergies. It makes me cringe. 

How can pet parents find a hypoallergenic dog shampoo when the marketing of it is so inconsistent? 

We are going to arm you with knowledge of what to look for in a hypoallergenic dog shampoo. 

What Is Hypoallergenic Dog Shampoo?

Just like humans, dogs can have sensitive skin, allergies, or other skin conditions that require gentle and soothing care during bath time.

In the ideal world, hypoallergenic dog shampoo is specially formulated to minimize the risk of allergic reactions and skin irritations in dogs.

Hypoallergenic dog shampoos should be formulated to be mild and free from common allergens, making them a safer option for dogs with skin sensitivities.

Let's dig into this a little deeper.

What Makes a Dog Shampoo Hypoallergenic?

Hypoallergenic dog shampoos should distinguish themselves through several key characteristics:

  1. Gentle Ingredients: Hypoallergenic shampoos should use mild, non-irritating ingredients that are less likely to trigger allergies or skin sensitivities. These products should exclude harsh chemicals, synthetic fragrances, and artificial colors.

    I did a quick Google search on hypoallergenic dog shampoo and selected one of the first products that came up to look up the ingredients. Here is what I found: 

    INGREDIENTS: Water, ALES, SLES, Coco Betaine, Cocamide DIPA, Cosmetic Grade Aminomodified Silicone-Polyether Copolymers, Babassuamidopropyl Betaine, Hydrolyzed Wheat Protein, DMDM Hydantoin, Glycerol, Proprietary Spearmint & Peppermint Botanical Essence, FD&C Blue #1 & Yellow #5, Citric Acid.  Should this product be marketed as hypoallergenic? In my opinion, absolutely not. It contains multiple ingredients that have known links to skin irritation or allergies, contains artificial fragrance and artificial colors! 

  2. Allergen-Free: Hypoallergenic shampoos should be formulated to be free from common allergens, such as parabens, sulfates, and dyes, which can irritate a dog's skin and coat. Again, if we look at that same product example I found in the Google search, we see a manufacturer who is not following this guideline by including both a formaldehyde based preservative (DMDM Hydantoin) and artificial dyes.

  3. Moisturizing Components: These shampoos should incorporate natural moisturizing agents like aloe vera, saponified organic oils, or gentle essential oils that will help to soothe and hydrate the skin, relieving dryness and itching. Using that same example, we see ingredients like Coco Betaine which is known to cause skin irritation on sensitive skin.

Why Choose Hypoallergenic Dog Shampoo?

There are several compelling reasons to choose hypoallergenic dog shampoo for your pet:

  1. Sensitive Skin Care: If your dog has sensitive skin or allergies, a hypoallergenic shampoo for dogs is a gentle and effective way to keep their skin and coat healthy without exacerbating existing issues.

  2. Reduce Allergic Reactions: Hypoallergenic shampoos reduce the risk of allergic reactions by using ingredients that are less likely to cause an issue.

  3. Natural Ingredients: Many hypoallergenic shampoos, like 4-Legger's organic options, use natural and organic ingredients that are kind to both your pet and the environment.

  4. Improved Coat Health: Regular use of hypoallergenic shampoo can lead to a shinier, healthier coat, since it does not strip the natural skin oils or cause dryness.

Selecting the Best Hypoallergenic Dog Shampoo

We've seen in this article that dog shampoo manufacturers clearly don't agree on the use of the word hypoallergenic.

In my opinion, many manufacturers use the word hypoallergenic as a marketing term, not a true reflection of the ingredients in the product. 

This means as pet parents, you have to perform your due diligence to carefully review the ingredients and validate each one really is safe and unlikely to cause skin irritation or an allergy.

You can use the Pet Shampoo Ingredient Database to make this task super easy! Simply use the dropdown menu to go to the correct page using the first letter of the ingredient name and scroll down to find the ingredient. You'll be an able to quickly identify if that ingredient has any links to potential health issues!
