The 8 Best Shampoos for Shih Tzus

1. Hepper Colloidal Oatmeal Pet Shampoo – Best Overall

We have chosen Hepper Colloidal Oatmeal Pet Shampoo as our favorite shampoo for Shih Tzus. We love its simple, all-natural ingredient list made without the use of harsh dyes, fragrances, or soaps. This pH balanced shampoo gently washes away dirt, dander, and excess hair while hydrating your pups skin and coat.

Heppers lightly scented oatmeal shampoo is effective in lifting odors trapped in your pets fur without masking them with heavy perfumes. Any easy win for your Shih Tzus sensitive nose!

Overall, this is our top pick for Shih Tzu shampoo!

At Dogster, we’ve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool pet company!

2. Espree Silky Show Aloe Vera Shampoo

The best budget shampoo for Shih Tzus is the Espree Silky Show Aloe Vera Shampoo. The shampoo is affordable and made in the USA. If your Shih Tzu’s skin becomes easily irritated, this shampoo contains aloe vera to help soothe their skin and make them feel much better after bathing. The shampoo is also all-natural and uses organic ingredients.

The only drawback to this shampoo is that some users said it’s not as effective as it should be when it comes to getting that stinky smell off your Shih Tzu at bath time. All in all, however, for its affordability, this is a great choice.

3. Petpost Whitening Shampoo For Dogs

Our next pick is Petpost Whitening Dog Shampoo. This shampoo is made in the USA and is also all-natural, like many of the dog shampoos on our list. This one comes with a 100% guarantee and has a pleasant, fresh watermelon scent that will leave your Shih Tzu smelling fresh and clean. If your Shih Tzu is mostly white, then this is the perfect shampoo as it contains whitening agents.

It does take a few baths for the whitening to take effect, and a few pet owners reported not liking the scent of the shampoo. However, if your Shih Tzu is predominantly white, this could be the best choice of shampoo for you.

4. Buddy Wash Original Lavender & Mint Dog Shampoo

Buddy Wash Original Lavender & Mint Dog Shampoo is number four on our list. This shampoo is soap-free and the lavender and mint fragrance will do a lot to keep your pet calm during and after bath time. If you’re super busy, then the fact that this is a 2-in-1 shampoo and conditioner will make it even easier to bathe your little Shih Tzu. All-natural and made in the USA, this shampoo comes in three different scents to choose from and uses only pet-safe ingredients.

The only drawback to this shampoo is that it comes with no guarantee, and some pet owners reported that it doesn’t always work as specified.

5. 4-Legger Organic Shampoo For Dogs

4-Legger Organic Shampoo weighs in at number five on our list of the best shampoos for Shih Tzus. This shampoo uses only holistic, USDA-certified oils and is cruelty-free and eco-friendly to boot. It moisturizes, cleans thoroughly, and has a pleasing scent.

However, some pet parents reported that this organic shampoo is being too watery to use and that the smell of the shampoo was a bit overwhelming. However, with all the benefits this shampoo carries, it’s worth a shot for your Shih Tzu and still belongs on our list, in our opinion. The lemongrass smell and the aloe for sensitive skin are enough to give it our recommendation.

6. Healthy Breeds Deodorizing Dog Shampoo

Another great shampoo for Shih Tzus is Healthy Breeds Deodorizing Dog Shampoo. Not only is this brand bio-degradable, but it’s also cruelty-free.

The shampoo works to soothe your Shih Tzus’ sensitive skin while helping to calm them at the same time. The fact that this shampoo is all-natural is one of our favorite things about it—the shampoo is made in the USA and you don’t have to worry about ingredients that could hurt your pet. It works for all life stages, deodorizes your pup, and is soap-free.

The only drawback we saw to this shampoo is that it’s quite a bit more expensive than some products on our list, and some customers reported the fragrance being a little overpowering.

7. Earthbath Oatmeal & Aloe Shampoo

At number six on our list is Earthbath Oatmeal & Aloe Shampoo. Not only is this shampoo soap-free, but it also contains oatmeal to help with irritated skin. In addition, the shampoo comes in a biodegradable bottle, and the shampoo itself comes in 13 different formulas to choose from, meaning you should be able to find the perfect shampoo to keep your pup clean smelling fresh, and healthy.

Some pet parents reported the shampoo drying out their Shih Tzu’s skin, while others said that the smell of the shampoo is too strong. However, considering the shampoo comes in 13 different formulas, there should be one that works well for your Shih Tzu.

8. Rocco & Roxie Supply Co. Dog Shampoo

Last but not least, at number seven on the list is Rocco & Roxie Supply Co. Dog Shampoo. This shampoo comes in two sizes and is available in three formulas. While it’s not the best on our list, and it doesn’t come in tons of different formulas, it does have a 100% guarantee and many Shih Tzu parents reported liking it.

However, there were some pet owners who reported the shampoo as being super watery, having too strong of a smell, and even failing to lather. Nevertheless, the fact that it comes in three formulas and two sizes secured it a spot on our list.

Buyer's Guide: Selecting the Best Shampoo for Shih Tzus

Now that you’ve read our reviews and know all the options for the best dog shampoos for Shih Tzus, you might still be wondering how you’re supposed to pick from all the options. Below, we’ll give you a couple of factors that you should consider when choosing a shampoo for your little friend.

Price

While we do have a few shampoos on our list that are affordable for all budgets, there are also a few that are quite expensive.

However, there are a few budget-friendly options we listed that we feel will work well for keeping your pup clean and smelling great without breaking the bank.

All-Natural
