Homemade Dog Shampoo: Natural, Gentle and Cheap
With a few kitchen ingredients you can mix a mild shampoo that is kind to your dog’s skin and costs a fraction of a store-bought natural product.
Making your own dog shampoo has three benefits: you know exactly what goes in, you leave out anything that irritates sensitive skin, and you save a lot of money. A simple base of plant soap, oats and aloe is enough for many washes. You only need to keep a few things in mind, because canine skin works differently from ours.
Why dog skin needs its own shampoo
Human skin is slightly acidic, with a pH around 5.5. A dog’s skin sits closer to neutral, roughly between 6.5 and 7.5. That is why human shampoo or shower gel dries out your dog’s skin and can trigger itching. A good dog shampoo cleans gently, keeps the protective acid mantle intact and skips harsh sulfates, artificial fragrance and preservatives. All of that is easy to recreate at home.
| Ingredient | What it does |
|---|---|
| Mild plant or castile soap | Cleans gently, made from coconut and olive oil, without aggressive surfactants. |
| Colloidal oatmeal (finely ground) | Calms the skin and relieves itching, a classic skincare ingredient. |
| Pure aloe vera gel | Adds moisture and cools irritated spots. |
| Virgin coconut oil | Makes the coat soft and brings shine. |
| Lukewarm water or chamomile tea | Dilutes the soap gently, chamomile soothes on top. |
What you save
High-quality natural dog shampoos quickly cost the equivalent of 25 to 40 euros for a small 250 to 400 millilitre bottle. You buy the raw ingredients once and mix fresh portions from them for weeks.
Example calculation
- One bottle of mild plant soap (around 470 ml) costs roughly 12 to 16 euros.
- Diluted with water, oats and aloe, that makes about 1.5 to 2 litres of finished shampoo.
- Each wash needs only 20 to 50 millilitres depending on dog size, just cents.
- Oats and coconut oil are often already in your kitchen.
Base recipe: gentle oat and aloe shampoo
This makes about 250 millilitres, enough for several washes on a medium-sized dog. Because the recipe has no preservatives, it is best to mix small amounts and keep them refrigerated.
Set the base
Pour 60 ml of mild plant soap with 150 ml of lukewarm water or cooled chamomile tea into a squeeze bottle.
Soothe the skin
Add 2 tablespoons of finely ground oats and 1 tablespoon of pure aloe vera gel to nourish and relieve itching.
Add shine
Stir in 1 teaspoon of melted coconut oil. Close the bottle and shake well before each use.
Apply
Wet the coat, massage the shampoo in gently, avoid eyes and ears, then rinse thoroughly. Keeps about 1 to 2 weeks refrigerated.
Dry shampoo for in between
When a full bath would be too much, a dry shampoo helps: massage finely ground oats into the dry coat, let them sit briefly and brush out thoroughly. This binds grease and odours without any water. For heavier dirt, mix in a small pinch of baking soda.
Shopping list of raw ingredients
You buy these once and then mix from them for a long time. Look for pure, unscented, organic quality, the fewer additives the better for your dog’s skin.

Mild plant or castile soap
Liquid, unscented, based on coconut and olive oil. The gentle cleansing foundation.

Virgin organic coconut oil
Makes the coat soft and glossy. A small amount is enough, one jar lasts a long time.
- Cold-pressed and virgin
- No additives
- Also for dry paw pads
Squeeze or pump bottle
For mixing, shaking and dosing. An empty, well-sealing bottle is all you need.
- BPA-free, opaque is a plus
- Pump or flip-top lid

These ingredients do not belong in dog shampoo
Many popular soap recipes for people are not suitable for dogs. Leave these out on purpose:
- Essential oils without veterinary advice. Tea tree, eucalyptus, citrus oils, pennyroyal, wintergreen, clove and cinnamon are considered toxic or strongly irritating for dogs.
- Garlic and onion. Popular in human soap recipes, but toxic to dogs. Nothing that reaches the skin or mouth either.
- Human shampoo and shower gel. Wrong pH, dries out the skin.
- Artificial fragrance and dyes. They irritate sensitive skin and the fine canine nose.
Keep eyes, ears and mouth clear while washing. Only bathe when necessary, washing too often weakens the skin’s natural protection. With redness, bald patches, intense itching or open skin, see your vet before applying anything.
How bath time stays relaxed
A little prep, a calm routine
- Lukewarm water, never hot, and a non-slip mat in the tub
- Brush before bathing to remove knots and loose hair
- Massage shampoo from neck to tail, head last and carefully
- Rinse thoroughly, leftover residue itches and sticks
- Dry well and keep the dog warm until the coat is dry
- Work with praise and calm, then bathing stays low-stress
Frequently asked questions
How often can I bathe my dog?
Only when needed, often every few weeks to months is plenty. Washing too often dries out the skin and weakens the acid mantle. In between, brushing or a dry shampoo helps.
Can I just use my own shampoo?
Better not. Human shampoo is tuned to a more acidic pH and irritates the more neutral canine skin. A mild, home-mixed dog shampoo is gentler.
Which essential oils are dangerous?
Among others tea tree, eucalyptus, citrus, pennyroyal, wintergreen, clove and cinnamon. They can be toxic or strongly irritating for dogs. When in doubt, leave essential oils out entirely.
How long does homemade shampoo keep?
Without preservatives about 1 to 2 weeks in the fridge. Better to mix small fresh batches and shake before each use.
Does it help with itchy skin?
Oats and aloe have a calming effect and can ease mild itching. If there is more behind it, such as an allergy or parasites, have it checked by a vet.
