Organic Lemongrass & Aloe Hypoallergenic Dog Shampoo

Many shampoos marketed as “natural” still contain synthetic preservatives, artificial fragrances, or detergent-based surfactants.

4-Legger dog shampoo is certified organic to USDA food standards, verified by a third party. This means every single ingredient has been independently audited for purity and safety — a standard that mass-market brands do not meet.

When you read our label, you’ll recognize every ingredient as a real plant or oil, not a chemical compound.

4-Legger contains zero synthetic chemicals — period. You won't find any of the following in our formula:

• Parabens
• Sulfates or detergents
• Synthetic fragrances
• Artificial thickeners
• Artificial colors or dyes
• Petroleum derivatives
• Phthalates
  

Every ingredient we use is either USDA Certified Organic or naturally derived. You can look up every single ingredient at PetShampooIngredientDatabase.com — because we have nothing to hide.

Yes, it is!

Hypoallergenic dog shampoo means it is unlikely to cause a skin reaction and safe to use on dog's (or their humans) who have very sensitive skin.

4-Legger is specifically formulated to be hypoallergenic, meaning it’s unlikely to trigger allergic reactions. Our organic aloe vera, coconut oil, and jojoba oil actively soothe irritated, itchy skin, while the absence of synthetic fragrances, dyes, and sulfates removes common allergy triggers.

Thousands of our customers report significant improvement in their dog’s allergy symptoms after switching to 4-Legger.

Yes, absolutely. 4-Legger is gentle enough for newborn puppies, senior dogs, and even cats. Because every ingredient is certified organic and free of synthetic chemicals, there are no harsh irritants that could harm sensitive or aging skin. Many of our customers use it on puppies as young as 8 weeks old.

4-Legger doesn’t contain sulfates or synthetic detergents — the chemicals that create the thick, foamy lather in conventional shampoos. Those same chemicals strip your dog’s skin of natural oils and can cause dryness, irritation, and allergic reactions.

Our formula lathers beautifully when you use the right technique: apply a small amount and add more water (not more shampoo) to build a rich, effective lather. For the easiest experience, pair your shampoo with our foaming bottle, which infuses air to create a luxurious foam with less product.

Yes, 4-Legger is a concentrated formula. A 16oz bottle typically provides 15–20+ baths for a medium-sized dog (30–50 lbs). For larger dogs, expect 10–15 baths.

The thin consistency is by design — we don’t add artificial thickeners to make the bottle feel "full." Every drop is active, working ingredients. Many customers find they use far less product than expected, making it a better value per bath than thicker, diluted alternatives. If the consistency bothers you, we recommend using one of our foamer bottles. They make the shampoo look like shaving cream and it is super easy to apply!

Start by thoroughly wetting your dog’s coat with warm water. Apply a small amount of shampoo and gently massage it into the coat, working from head to tail while avoiding the eyes.

Because this is a concentrated, natural formula without synthetic thickeners, it has a thinner consistency than conventional shampoos. For best results, add more water—not more shampoo—to help create a light, effective lather. Rinse thoroughly and repeat if needed.

For an even easier application and richer foam, you can dilute the shampoo in a 4-Legger Foamer Bottle. This helps distribute the shampoo more evenly, reduces product use, and makes bath time quicker and more enjoyable for both you and your dog.
