13 Best Shampoo for Shih Tzus 2026: Soothe Dry Itchy Coats

This all-in-one shampoo cleans, conditions, detangles, and moisturizes at a budget price, saving you from buying separate products. It lathers well with small amounts and rinses clean, leaving the coat soft and shiny. The lavender-chamomile scent is calming and not overpowering. However, it is not the right choice if your Shih Tzu has dry, itchy skin — the oatmeal formula in this review set addresses that better. Some dogs with very sensitive skin may react to the fragrance, so avoid this if your dog has a known lavender allergy or extreme sensitivity. It works well for Shih Tzu owners on a budget who want a spa-like bath experience for normal to mildly dry coats.

This earthbath set combines colloidal oatmeal, organic shea butter, and aloe vera to deliver exceptional softness and conditioning for thick, long coats like those of Shih Tzus. The vanilla and almond scent is pleasant without being overpowering. Best for owners willing to invest in a matched shampoo and conditioner for regular use, especially if dry, itchy skin is a concern. The premium price and lack of tearless formulation mean it's not a budget option and requires care around the eyes during face baths.

This shampoo produces satisfying suds that rinse cleanly from a Shih Tzu's coat, leaving it soft and fresh-scented. The tearless formula makes washing around the eyes straightforward. However, the fragrance can be strong for scent-sensitive owners, and a small percentage of dogs may experience mild skin irritation — a patch test is wise before committing.

This professional-grade concentrate delivers exceptional value per wash for frequent bathers, leaving the coat soft, shiny, and easy to brush with a pleasant plum scent that lasts. However, it is not tearless and can cause eye irritation if it gets in the eyes, plus the premium-priced bottle requires careful dilution. This suits owners who bathe their Shih Tzu often and are comfortable keeping the product away from the face.

This shampoo leaves a lasting designer fragrance and a silky, shiny coat, but the premium cost and potential for skin dryness make it a poor fit for Shih Tzus with sensitive skin — better suited for short-coated dogs where the risk is lower.

The Wahl Oatmeal Itch Relief shampoo targets dry, itchy skin with colloidal oatmeal, coconut, and lime verbena, leaving coats soft and shiny without parabens or sulfates. For Shih Tzus prone to flaking or irritation, this formula addresses the root cause rather than just masking symptoms — a distinction that sets it apart from general all-in-one shampoos.

This budget-friendly choice is for owners who need a dedicated oatmeal formula without paying a premium. The coconut lime scent lasts through the week for most dogs, though a small percentage may find it fades faster between washes. Because the formula is not tearless, avoid direct contact with eyes during bath time.

Baking soda neutralizes strong smells while the tearless formula allows worry-free washing around eyes and face. For a Shih Tzu that gets smelly between baths, this shampoo lathers well and comes at a low cost per wash. The kiwi blossom scent is noticeable and some dogs with sensitive skin may develop dryness or irritation after use, so it works best when your primary need is odor control rather than extra moisturizing.

Unlike the top pick focused on itch relief, this shampoo uses silk proteins to lift yellowing and brighten white coats. It leaves fur silky soft and is gentle enough for frequent baths at a budget-friendly price. Best for Shih Tzu owners who prioritize brightening over stain removal — whitening results may vary and deep tear stains likely need a dedicated product. Those with extremely sensitive skin should patch test first due to minor irritation reports.

This shampoo delivers a sweet baby powder scent that lingers on the coat for days, and its concentrated formula means a small amount goes far. However, bottles have been known to arrive with leaks or broken nozzles, which can be a hassle. Best suited for owners who prioritize that lasting scent and are willing to accept shipping variability.

Oliver's Choice combines oatmeal, aloe, and shea butter to moisturize dry skin and soften coats, with a pleasant oatmeal-coconut scent. However, it costs more per ounce than the top-pick Wahl Oatmeal, and some dogs may still experience incomplete itch relief or find the fragrance too strong.

This tearless shampoo is a budget-friendly choice for Shih Tzu puppies with sensitive skin, safe around eyes. However, the thin, watery consistency produces little lather, meaning you'll need extra product per wash. The mild scent may disappoint if a noticeable fragrance is desired.

This budget-friendly shampoo uses optical brighteners to lift yellowing and restore brightness to white coats without bleach or peroxide, and it leaves fur soft with a pleasant citrus scent. However, those same brighteners can irritate sensitive skin, and whitening results are variable. This is not a safe choice for any Shih Tzu with a history of skin allergies or for owners who expect consistent stain removal.
