Dog baths provide many benefits, including removing dirt and grime, eliminating odors, and creating special human-animal bonding time. A bath with one of the best medicated dog shampoos can also treat skin problems from allergies and infections and provide much-needed relief from skin irritation.

For this guide, we evaluated 15 medicated shampoos for dogs, according to our veterinarian-informed selection criteria. Our top pick is Veterinary Formula Clinical Care Antiparasitic and Antiseborrheic Medicated Shampoo. This shampoo treats several conditions, from parasitic and fungal infections to flaky and itchy skin, and moisturizes dry skin.

As a veterinarian, I understand the complexities of skin conditions in dogs. Even with this curated list of shampoos, you should first visit your veterinarian, who will diagnose your dog's skin condition and recommend a medicated dog shampoo if appropriate. Be aware that a prescription medicated dog shampoo may be the best choice over an over-the-counter (OTC) shampoo. Always follow your veterinarian's instructions for using any shampoo. If you're looking for a nonmedicated formula, we cover them in our guide to the best dog shampoos.

Best overall

Veterinary Formula Clinical Care Antiparasitic & Antiseborrheic Medicated Shampoo

This is a mild-scented shampoo that treats various skin conditions while hydrating and healing the skin.

The inevitable irritation created by skin problems can make dogs feel miserable and needs to be resolved quickly and effectively.

"A medicated shampoo is used to treat numerous skin conditions, such as bacterial and fungal infections and allergic disease," says Dr. Joya Griffin, a veterinary dermatologist at Animal Dermatology Group in Louisville, Kentucky. However, just treating the condition isn't enough. The skin also needs moisturizing to be restored to good health.

Veterinary Formula Clinical Care Antiparasitic and Antiseborrheic Medicated Dog Shampoo treats multiple skin conditions, including parasitic and fungal infections, seborrhea (greasy, flaky, itchy skin), and general dermatitis (skin inflammation). It also contains oatmeal and allantoin to soothe, hydrate, and heal the skin. This shampoo's ability to treat multiple skin conditions and heal the skin, all at a reasonable price, made it our top choice.

The shampoo contains salicylic acid, coal tar, and micronized sulfur, which work together to treat skin infections and reduce seborrhea symptoms. "Shampoos that contain sulfur or salicylic acid can be used for seborrheic conditions," says Griffin. However, she warns that salicylic acid can cause dryness and irritation.

Free of soap and dyes, this shampoo is safe for puppies at least 12 weeks of age and does not remove the best flea treatments for dogs that are topical medicines.

Best for bacterial infections

Veterinary Formula Clinical Care Antiseptic & Antifungal Mediated Shampoo

This shampoo quickly treats bacterial and fungal skin infections and soothes the skin with natural aloe vera and lanolin.

What we like
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Free of soap
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Treats multiple types of skin infections
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Reduces itching and flaking

Bacterial skin infections, broadly termed "pyoderma," have several potential causes. These causes include a break in the skin from injury or constant scratching, a change in the skin's normal bacterial population, and excessive moisture on the skin.

Veterinary Formula Clinical Care Antiseptic and Antifungal Shampoo contains the antibacterial agent benzethonium chloride to treat bacterial skin infections, along with ketoconazole to treat fungal infections. Many medicated dog shampoos that treat skin infections contain antibacterial and antifungal agents.

This shampoo was our top choice for several reasons. For example, it effectively treats both antibacterial and antifungal infections. In addition, the shampoo contains lanolin to reduce skin itching and flaking, as well as aloe vera to soothe and heal itchy and irritated skin. Also, the shampoo does not remove topical flea and tick treatments. To have these positive product characteristics, it impressed us that the shampoo costs less than $10 for 16 ounces.

Although the shampoo does not lather as thickly as other medicated dog shampoos we reviewed, it has a mild, non-medicinal scent and rinses out easily. It is safe for puppies at least 12 weeks of age.

Best for fungal infections

Pet MD Medicated Shampoo for Skin Conditions

Pet MD Medicated Shampoo treats fungal and bacterial skin infections and provides healing for dry skin and minor skin injuries.

What we like
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Contains ketoconazole to treat fungal infections
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Contains colloidal oatmeal and aloe vera to soothe and moisturize the skin
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Safe for puppies at least 12 weeks of age
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Helps heal minor skin injuries
  • Check mark icon A check mark. It indicates a confirmation of your intended interaction. Light mint scent
What we don't like

Fungal skin infections, such as ringworm and yeast dermatitis, occur less commonly than bacterial skin infections in dogs. Our top choice for medicated dog shampoos for fungal infections is Pet MD Medicated Pet Shampoo. Not only does it contain the antifungal agent ketoconazole, but it also contains colloidal oatmeal and aloe vera to soothe and moisturize infected skin that has become itchy and irritated.

An additional ingredient, chlorhexidine, is an antibacterial agent that can treat skin conditions like bacterial dermatitis. Chlorhexidine also has antifungal properties, giving the shampoo a slight edge in antifungal activity over Veterinary Formula Clinical Care Antiseptic and Antifungal Medicated Shampoo. In addition to these functions, chlorhexidine can help treat minor skin injuries, such as those caused by superficial cuts and insect bites.

Safe for puppies at least 12 weeks of age, the shampoo has a pleasant peppermint scent that can last long after the bath. If you have a white dog, be aware that the shampoo could discolor your dog's fur.

Best flea and tick

Adams Plus Flea and Tick Shampoo with Precor

Adams Plus kills fleas, flea eggs and larvae, ticks, and lice for up to 28 days while soothing dry, irritated skin.

Flea and tick control is a cornerstone of responsible pet ownership. Veterinarian-prescribed flea and tick preventatives are the best choice for preventing these pesky parasites, and pet owners should use them as the primary form of flea and tick prevention.

Flea and tick shampoos have a role to play, though. Dr. Tierra Price, a shelter veterinarian and founder of BlackDVM Network, notes that these shampoos can be very effective at killing adult fleas and ticks. Our experts concur, however, that flea and tick shampoos are not good at prevention. "Flea and tick shampoos have very little residual activity an...
