How To Pick the Best Dog Shampoo

Dog shampoos are formulated specifically for canines. 

Because dogs and humans have different skin pH levels and sensitivities, a pet-specific shampoo is the best way to cleanse your dog’s skin and coat without leaving it dry, itchy, or dull.   

To safely and effectively clean your dog, you can’t use just any shampoo.  

Human shampoos may contain soaps, sulfates, parabens, and silicones that can irritate your dog’s skin.   

Human shampoos are not safe for dogs for many reasons, but primarily because human skin is more acidic. Shampoos made for humans can strip a dog’s natural protective barrier, leaving it vulnerable to infections, irritation, and environmental damage. 

Dog shampoos are designed to gently remove dirt and oils without stripping the skin, helping prevent odors caused by yeasty overgrowth or bacterial infection.  There is a normal amount of bacteria and yeast on a dog’s skin, but too-harsh shampoos cause it to overpopulate.   

However, you should consider your dog’s age, health, and coat condition when picking a shampoo. If your dog has any hair loss or irritation, for example, you can ask your vet about a specialty shampoo.  

For regular use, pick a soap-free dog shampoo free of sulfates or parabens, as they can be drying to your dog’s skin and coat.  

Look for natural, plant-derived ingredients that moisturize or add shine.  

The best flea and tick shampoos kill parasites on contact, but check with your veterinarian before using these medicated formulas.  

Soothing ingredients, such as aloe vera or lanolin, can help reduce irritation and scratching from bites.  

Dogs with sensitive skin need a gentle, effective shampoo without harsh ingredients, such as sulfates, parabens, phthalates, artificial colors, or strong fragrances.  

Choose formulas with soothing, plant-derived ingredients, such as colloidal oatmeal, coconut oil, and shea butter. 

Puppies need a specially formulated shampoo, because their skin has a lower pH level than adult dogs.  

Pick a puppy shampoo that is gentle with natural, moisturizing ingredients like coconut oil, oatmeal, and milk or soy proteins. A tear-free formula is a must in case your playful pup gets suds in their eyes.  

If your dog has a medical issue—such as a hot spot, rash, skin infection, or even just a stinky smell—a medicated shampoo with active ingredients to treat bacterial or fungal infections may help.  

Ask your veterinarian whether a medicated shampoo should be part of your dog’s treatment.  

You probably already brush your dog regularly, but the right shampoo can also help reduce your pet’s shedding.  

Use a de-shedding shampoo every two to four weeks to help release loose fur and strengthen hair follicles for a healthier coat. 

Hypoallergenic dog shampoos minimize ingredients that could trigger allergies. Look for dye-free, fragrance-free formulas made with naturally derived ingredients with a soothing effect, such as oatmeal or aloe or those with vitamin E which is a great antioxidant to protect the skin.  

Deodorizing dog shampoos help banish doggy odor by removing the buildup of natural skin oils that become a little stinky.  

These shampoos often contain baking soda, probiotics, or botanical extracts to leave your dog smelling clean.  

Whitening dog shampoos help breeds like Westies and Maltese maintain their bright coat. They typically contain proteins, enzymes, or optical brighteners to enhance color.    

A safe whitening shampoo for dogs should not contain bleach. Never use a product with bleach on your dog.  

Here’s what to consider when choosing a shampoo for your dog:  

• Make sure it’s a soap-free formula without sulfates, such as sodium lauryl sulfate, and without parabens.  
• Stick with light, natural fragrances (if you’ve ever seen your dog get the zoomies after a bath, it’s probably because they’re trying to get rid of a strange new scent!). 
• Consider your dog’s life stage and any medical needs (for example, if they’re a puppy or prone to skin issues).  
• Look for bonus ingredients like silk protein, aloe vera extract, colloidal oatmeal, coconut oil, and botanical extracts.  

At the end of the day, a bath might be a trying time for your dog, but once they start getting compliments, attention, and a treat or two, it’ll be worth it.  

Can you use human shampoos on dogs? 

No. Dogs and humans have different skin pH levels, skin sensitivities, and hair follicle structures, so avoid using human shampoo on your dog.  

Can you use dish soap on dogs?  

No, except in rare situations to treat fleas in very young puppies who are too young for flea prevention. Otherwise, choose a dog-formulated shampoo.  

Can I use baby shampoo on my dog? 

No. Baby shampoo isn’t formulated for a dog’s skin pH or coat needs. However, a fragrance-free, tear-free baby shampoo can be a temporary substitute for puppy shampoo in a pinch.
