How to Make DIY Dog Shampoo with Oatmeal, Aloe Vera & Coconut Oil
Making your own dog shampoo lets you control the ingredients. There are no harsh chemicals, strong perfumes, or unknown additives. Ingredients like oatmeal calm irritation, aloe vera hydrates the skin, and coconut oil softens and adds shine.
Save for later
Dogs with sensitive skin often respond better to gentle, homemade formulas. Plus, making your own shampoo feels like a small, satisfying win for any pet parent.
What Each Ingredient Actually Does
| Ingredient | Benefits | Notes |
|---|---|---|
| Oatmeal (colloidal or ground) | Soothes itchy, inflamed skin and locks in moisture | Use finely ground oats or grind your own to a powder that dissolves easily in water |
| Aloe Vera | Hydrates, cools irritation, balances pH | Choose pure, additive-free gel (no alcohol, colors, or chemicals) |
| Coconut Oil | Softens coat, reduces flakiness, adds shine | Fractionated coconut oil is lighter; use small amounts to avoid greasiness |
What About the Clean Part? (Choosing a Gentle Base)
Dogs need a cleanser to remove dirt and oils. There are two main options:
- Unscented, diluted castile soap: Natural and effective. Dilute well before use.
- Pet-safe shampoo base: Pre-made, pH-balanced, and easy to use.
Dogs’ skin prefers a pH of 6.5–7.5, so avoid most human shampoos which are often too acidic.
Simple DIY Dog Shampoo Recipe
This recipe makes about 12–14 oz, enough for a few baths depending on your dog’s size.
Ingredients
- 1 cup warm water
- 1/3 cup unscented liquid castile soap or pet-safe shampoo base
- 1/2 cup colloidal oatmeal (or very finely ground oats)
- 2 tablespoons pure aloe vera gel
- 1–2 teaspoons melted coconut oil (or 1 tsp fractionated coconut oil)
- Optional: 1 teaspoon vegetable glycerin for extra moisture
Tools
- Blender or whisk
- Fine mesh strainer (optional)
- Squeeze bottle or jar with lid
Instructions
- Grind the oats until powdery. Test by stirring a teaspoon in warm water — it should cloud without grit.
- Mix warm water and soap gently to avoid excess foam.
- Whisk in aloe, coconut oil, and glycerin (if using). Blend lightly for smooth consistency.
- Add oatmeal last while whisking to prevent clumps. Strain if needed.
- Bottle, label with the date, and shake before each use.
- Store in the fridge up to 2 weeks. Discard if it smells off or separates.
How to Use It
Prep Your Pup
- Brush out tangles for easier shampooing.
- Place a nonslip mat or towel in the tub.
- Use lukewarm water — too hot can irritate, too cold is uncomfortable.
Bath Routine
- Wet your dog thoroughly to reach the skin.
- Apply shampoo from neck to tail, saving the face for last using a damp cloth.
- Massage for 2–3 minutes, focusing on itchy areas like belly, paws, and armpits.
- Rinse thoroughly until water runs clear to avoid residue.
- Dry gently with a towel or low heat if tolerated.
- Frequency: Bathe every 4–6 weeks for most dogs. Adjust based on coat type and activity level.
Customization: Tweak It for Your Dog
Dry, Flaky Skin
- Add 1 extra teaspoon glycerin.
- Use fractionated coconut oil to avoid heaviness.
- Rinse with diluted aloe water (1 tsp aloe in 1 cup water).
Oily Coats
- Reduce coconut oil to 1/2–1 teaspoon.
- Slightly increase soap and water to maintain consistency.
- Rinse extra thoroughly.
Sensitive or Allergy-Prone Dogs
- Patch test on a small area first and wait 24 hours.
- Keep formula simple: water + pet-safe base + oatmeal + aloe.
- Avoid essential oils to prevent irritation or toxicity.
Common Mistakes to Avoid
- Using too much oil → greasy coat
- Using human shampoos → too harsh
- Not rinsing enough → residue causes itchiness
- Adding essential oils → potential irritation or toxicity
- Ignoring storage rules → spoilage; small batches are safest
When to Call the Vet
DIY shampoo is great for mild skin issues. But if your dog has persistent redness, hair loss, scabs, odor, or constant scratching, consult a veterinarian. Medicated shampoos may be needed for infections, allergies, or other skin conditions.
FAQs
Can I use this shampoo on puppies?
Yes, dilute it, avoid the face, rinse thoroughly, and keep baths short.
Is oatmeal safe for dogs with grain allergies?
Most dogs tolerate oats, but skip if your dog has known grain sensitivity. Patch test first.
Can I add essential oils like lavender?
Not recommended. Many essential oils irritate dogs or can be toxic if licked. Use pet-safe scented products instead.
What if my dog has fleas?
This shampoo soothes skin but won’t remove fleas. Use vet-approved treatments and control the environment.
How long does the shampoo last?
1–2 weeks in the fridge. Shake before use. Discard if spoiled.
Can I store it at room temperature?
No. Natural ingredients spoil easily. Refrigeration is best. For shelf-stable options, use a preserved pet-safe base.
