What You Need
- 1 cup rolled oats
- 1 quart warm water
- 1/4 cup mild unscented dish soap or gentle castile soap
- 1/2 tablespoon coconut oil
- A small squeeze of lemon juice
- Blender
- Mixing bowl
- Empty pump bottle or shampoo bottle
Step-by-Step: How to Make DIY Oatmeal Dog Shampoo
Step 1: Blend the Oats
Add 1 cup of rolled oats to a blender. Blend until the oats become a fine powder. This helps the oatmeal mix smoothly into the shampoo.

Step 2: Add Warm Water
Pour 1 quart of warm water into a mixing bowl. Add the oat powder and stir well until the mixture looks cloudy and smooth.

Step 3: Add Mild Soap
Add 1/4 cup of mild unscented dish soap or gentle castile soap. Stir slowly to avoid creating too many bubbles.

Step 4: Add Coconut Oil and Lemon
Mix in 1/2 tablespoon of coconut oil and a small squeeze of lemon juice. Coconut oil can help soften the coat, while lemon adds a fresh scent.

Step 5: Mix Until Smooth
Stir everything together until the shampoo becomes creamy and well combined.

Step 6: Pour Into a Bottle
Use a funnel to pour the shampoo into a clean pump bottle or shampoo bottle.

Step 7: Shake Before Use
Shake the bottle gently before each bath because natural ingredients may separate.

How to Use It
Wet your dog’s coat with warm water. Apply a small amount of shampoo and massage gently into the fur, avoiding the eyes, ears, nose, and mouth. Let it sit for 2–3 minutes, then rinse very well.
Safety Tips
Use only mild, unscented soap. Avoid essential oils unless your vet approves them. Do not use this shampoo on open wounds or irritated skin. If your dog has allergies, skin problems, or strong itching, ask a veterinarian first.
Final Thoughts
DIY oatmeal dog shampoo is a simple homemade grooming recipe that can help keep your dog’s coat clean, soft, and fresh. With only a few ingredients, you can make a gentle dog shampoo at home for regular bath days.
