What to Look For in a Shih Tzu Shampoo
- Made for dogs. VCA Animal Hospitals explains that human skin is more acidic (pH 5.2 to 6.2) than dog skin (pH 6.2 to 7.5). Human shampoo can disrupt a dog’s protective skin barrier and strip natural oils.
- Gentle and fragrance-light. Unscented or lightly scented formulas are a good choice for sensitive skin.
- Soothing ingredients. Many gentle dog shampoos use colloidal oatmeal or aloe for dry skin.
- A conditioner for long coats. A conditioner helps the brush glide through a long coat and can reduce tangles.
Be careful with essential oils. The Pet Poison Helpline notes that concentrated tea tree oil is toxic to pets, although commercial pet products with less than 1 to 2 percent are generally safe when used as directed. Never add essential oils to your dog’s shampoo yourself.
Itchy, red, or smelly skin? A shampoo cannot fix an underlying allergy or infection. Medicated shampoos should be used only when your vet recommends them. See our guide to itchy skin in Shih Tzus.

How to Bathe a Shih Tzu Step by Step
The best shampoo will not help much if the bath itself tangles the coat. The American Shih Tzu Club gives simple advice for pet dogs. Follow these steps.
- Brush out every mat first. Water tightens mats. The American Shih Tzu Club says to brush the dog out thoroughly before the bath. See our brush guide for the right tools.
- Use lukewarm water. Test it on your wrist. Place a cotton ball loosely in each ear opening to help keep water out, and remove it after the bath.
- Shampoo gently. Squeeze the shampoo through the coat. Do not scrub in circles, which creates tangles. The club suggests two soapings with a shampoo made for dogs.
- Rinse very well. Leftover shampoo can irritate the skin. Keep rinsing until the water runs clear.
- Condition. The club suggests diluting a capful or two of conditioner in a quart of warm water and pouring it over the coat.
- Blot, do not rub. Wrap your dog in a towel and press out the water.
- Blow dry while brushing. The club recommends drying a Shih Tzu with a blow dryer. Use a low, warm setting and brush in sections as you dry.

How Often Should You Bathe a Shih Tzu?
For a pet Shih Tzu, the American Shih Tzu Club says a bath about every three weeks is typical. Dogs in a short puppy cut may go a little longer. Dogs with skin problems may need a different schedule. If your vet prescribes a medicated shampoo, follow their schedule instead.

Frequently Asked Questions
Can I use human shampoo on my Shih Tzu?
It is not recommended. VCA Animal Hospitals notes that human skin is acidic, with a pH of about 5.2 to 6.2. Dog skin is closer to neutral, at about 6.2 to 7.5. Human shampoo can strip natural oils and irritate your dog’s skin. Choose a shampoo made for dogs.
How often should I bathe my Shih Tzu?
The American Shih Tzu Club says a pet Shih Tzu will usually need a bath about every three weeks. Brush the coat daily between baths. If your dog has a skin condition, follow the bathing plan your vet gives you.
Does my Shih Tzu need conditioner?
Most Shih Tzus benefit from it, especially dogs with a long coat. A conditioner makes the coat easier to brush after the bath and helps reduce breakage. Rinse it out well unless the label says it is a leave-in product.
What is the best shampoo for a Shih Tzu with sensitive skin?
Look for a fragrance-free or unscented formula with gentle, soothing ingredients such as oatmeal or aloe. Our top pick for sensitive skin is an unscented oatmeal shampoo. If your dog is itchy, red, or smelly, see your vet first. Those signs can point to allergies or infection that shampoo alone will not fix.
Is tea tree oil shampoo safe for Shih Tzus?
Pet Poison Helpline warns that concentrated tea tree oil is toxic to dogs. Never apply the oil itself to your dog. Small dogs are at higher risk. Ask your vet before using any product that contains tea tree oil.
