Our Review

When you’ve tried everything else, try Dechra’s Miconahex + Triz Shampoo. This 8-ounce bottle may be on the small side, but it is an incredibly effective topical antifungal and antibacterial. You can use this shampoo on your cats, dogs, and horses with yeast dermatitis and other skin infections.

This may cause your pet’s skin to dry out after using this product frequently. While it does have moisturizing properties, the harsh medications that help treat skin infections may do this as well. Be aware that if your dog has particularly sensitive skin; it will work, and it may even help repair damaged skin. However, it can also easily dry them out and make them itchier.

Duoxo is one of the names that vets reach for first to help treat tough infections that aren’t affected by diet or lifestyle changes. Though this is a small bottle, it does great work to make sure that your dog’s skin remains clean and recovers quickly from septic issues, bacterial infections, and fungal infections.

This unscented shampoo has multiple active ingredients to cover all the ground that you need. You can use this shampoo on cats and dogs, though it may be a bit harsh if used frequently due to the medications. Still, if your dog has a diagnosed condition that hasn’t cleared yet, give Duoxo’s shampoo a try.

PetMD’s Medicated antibacterial and antifungal can be the single shampoo you use for all of your dog, cat, and horse needs. This shampoo treats a wide variety of infections, abrasions, and more – it can be extremely useful in many situations, so it’s good to have on hand. You get a lot of product for the price as well – nearly double the amount of certain leading competitors. If your dog has a light-colored coat, the bright red formula may dye them a pinkish color for a time. Unfortunately, there’s no way to avoid this and also get the desired effects.

Vetoquinol has a strong medicinal smell, but don’t let that get to you. It’s effective for cats, dogs, and horses to treat a variety of skin conditions and infections. A unique blend of miconazole (to fight yeast) and chloroxylenol (to fight bacteria) helps balance out the treatment to suit your dog’s unique skin issues. This shampoo is frequently recommended by vets.

Unfortunately, this means that it’s also expensive. However, you can save by purchasing a larger amount. This may be beneficial if you have more than one dog to treat. This formula works to protect damaged skin and heal infections that may be keeping your dog itchy and uncomfortable.

Nootie may not be a well-known brand for medicated shampoo, but it does help most dogs with their skin irritations, infections, and more. With a strong (and mostly pleasant) scent, this shampoo can make your dog more comfortable while also making them smell and look great. The active ingredients are both really strong and work together to fight bacteria and fungal infections.

The smell is unique for a medicated shampoo. Some people love it, some hate it – how you like it is entirely up to you. This shampoo is packed with healing oils and soothing ingredients in addition to the medication to help with a variety of skin infections. Most dogs will find relief right away!

Our Review

Arava’s Natural Medicated Dog Shampoo says that it contains medication but contains very little. All of the ingredients are natural with no harsh chemicals, so it may be perfect for pet owners who want a more holistic approach. Most of the ingredients in this shampoo are soothing and therapeutic. However, some ingredients may result in adverse reactions. This can be problematic, especially if you don’t know exactly what your dog is allergic to.

However, it works well for some dogs. The essential oils and natural ingredients can be a non-irritating alternative to some of the medications contained in most anti-fungal shampoos. Arava also contains dead sea minerals, known for their healing properties across the world. If you want a holistic and natural way to get your dog feeling soft and free of those skin conditions, this might be a great choice.

It’s a powerful cleaner with a lot of properties that might make it the right choice for your dog if you can stand the price tag.

Stratford’s Keto-C shampoo is gentle and effective, working to remove dermatological conditions such as yeast, ringworm and similar conditions. When your dog has a skin condition or an infection, you can use just a little of this shampoo to heal the skin and kill fungus and bacteria. No more harmful itching or pain for your dog, cat, or horse!

This shampoo also cleans deep and removes the odors associated with these skin conditions. It doesn’t take much of this shampoo, as it’s fairly concentrated. Following the directions exactly will yield the best results. When you want your dog, cat, or horse’s skin and fur to be soft and restored, this is the shampoo to use. Note that it is not meant to be used frequently, as it does contain powerful medicines to fight these infections.

Medicated shampoos can be a bit hit-or-miss depending on your dog and their specific tolerances to certain chemicals and treatments. However, KetoWELL by VetWELL has fewer reported cases of skin irritation than any of the other medicated shampoos that we’ve looked at. This shampoo pulls double-duty, helping to clean, disinfect, fight infections, and soothe irritated skin at the same time.

The shampoo itself is thick, and a little goes a long way. The mint smell might not appeal to everyone, but it may be preferable to a strong medicinal smell. You can use this shampoo to help your dogs, cats, and horses overcome painful skin conditions and restore irritated skin at the same time.

Our Review

Curaseb’s Chlorhexidine shampoo contains a higher concentration of chlorhexidine, an antibacterial and antifungal medication that is present in most of these shampoos. This means that it works well for tough cases, but may leave sensitive dogs itching or irritated. The soap doesn’t lather a lot, but that doesn’t mean it isn’t working.

This veterinary-strength formula works on both dogs and cats. It works to remove tough odors while it heals hotspots and other skin conditions. If your dog has been in discomfort and nothing else has worked, this stronger formula may be the answer to those tough issues. The blueberry scent will linger on your dog’s fur, making them smell and feel great

How to Choose:

When your dog has a dermatological fungal infection, you want to make sure that you’re getting the right shampoo to treat the problem. When combined with the right oral medications and the guidance of a veterinarian, an anti-fungal shampoo can help make your dog comfortable and itch-free. Here, we’ll take a look at the most common fungal infections, common ingredients to look for, and other factors to consider when purchasing an anti-fungal shampoo.

Veterinary Diagnosis Is Important

Keep in mind that multiple different conditions may display the same symptoms as a yeast infection. Some may be more serious or require completely different treatments than a fungal infection. For that reason, you must be sure to get a veterinarian’s diagnosis before embarking on a treatment plan. 

The vet may test your dog for yeast infection in many different ways, including a swab sample, skin scraping, or other non-invasive tests. Don’t hesitate to get your dog in to see the vet as soon as you possibly can to get a proper diagnosis before buying an anti-fungal shampoo. Most anti-fungal shampoos work better when they are used with other topical creams or oral medications. 

Treating a yeast infection often requires harsh chemicals, so it is of the utmost importance that you know what you’re treating before you start. This way, you can avoid harming your dog unnecessarily. 

What is Yeast Dermatitis?

Yeast dermatitis is the most common fungal skin infection for dogs. This condition can develop at any time. Most often, a change in circumstances, shampoos, and seasonal allergies may result in yeast dermatitis. 

Yeast is everywhere on your dog’s body. It’s on yours, too! Usually, the growth of yeast is kept in check by your dog’s immune system. However, any event that causes your dog’s immune system to work incorrectly (when it is fighting off allergies or illness, for example) can lead to an overgrowth of yeast on the surface of the skin. An increase in natural oil production can also be to blame for yeast infections. 

A veterinary diagnosis is always required to identify a fungal infection such as yeast dermatitis correctly. However, there are a few symptoms that may clue you in to your dog’s yeast infection. These include:

  • A musty odor on your dog’s skin and fur
  • Patches of dark pigmentation
  • Frequent ear infections
  • Itching
  • Redness
  • Moist skin
  • Scales
  • Thick skin 
  • Crusty or flaky skin

Keeping the skin dry isn’t easy, but it’s ideal for promoting speedy recovery. The use of shampoos that contain anti-fungal ingredients can work together with topical solutions to clear up the yeast infection on your dog’s skin.

What is Ringworm? 

Ringworm is another common fungal infection that affects your cats, dogs, and other pets. The name is misleading, as parasites do not cause ringworm infections, and there are no worms involved. 

Ringworm is a fungal infection that often grows in a circular pattern. The distinctive pattern is where the name comes from. It’s a common infection, and it is very contagious. If one of your dogs has ringworm, it’s best to prepare to treat the rest of them as well. 

Some common symptoms of ringworm include:

  • Scales
  • Dandruff
  • Dark skin pigmentation in infected areas
  • Hair loss
  • Boils
  • Kerions (abscesses) 
  • Brittle nails
  • Itchiness
  • Coarse coat
  • Inflammation

Ringworm is diagnosable by a vet and is treated by anti-fungal creams and topical solutions, as well as an oral medication in extreme cases. 

Common Antifungal Ingredients 

Three main ingredients typically occur in anti-fungal treatments: chlorhexidine, miconazole, and ketoconazole. Let’s take a look at what these medications do and what the difference between them is. 

  •  Chlorhexidine is a chemical used widely in mouthwashes for humans, but it helps your dog differently. This medication can strip oils out of the skin, killing yeast and drying out moisture as it goes. Anywhere from 2% to 4% chlorhexidine is effective at treating fungal infections on your dog’s skin. 4% is a bit strong and may be too much for dogs with sensitive skin when used topically. Chlorhexidine may dry your dog’s skin out, so make sure to moisturize after use and when the yeast infection has cleared.
  • Miconazole is a topical antifungal used (in dogs) to treat ringworm and other fungal infections. It does this by disrupting specific cellular processes, which stop fungal cells from being able to form. It can be a bit harsh on your dog’s skin, but it is a standard treatment for fungal infections such as ringworm. Miconazole is also used to treat yeast infections and ringworm-type dermatological conditions in humans
  • Ketoconazole is an oral and topical antifungal that is most effective for dogs, as it may rarely cause life-threatening conditions in cats. It is often prescribed for ear infections, ringworm, and fungal skin infections. It is used in shampoos and lotions and antifungal medication taken orally (with food). Ketoconazole is most often used alongside chlorhexidine to treat fungal and bacterial infections on your dog’s skin. 

What to Look for in an Antifungal Shampoo

What are some of the essential things to keep in mind when purchasing an anti-fungal shampoo? Here’s what you should be looking for as you shop. 

  • Active Ingredients

As we mentioned above, some active ingredients are specifically meant to treat fungal infections. Ingredients like chlorhexidine, miconazole, or ketoconazole may be a bit harsh, but they can deal with yeast infections like no other. Natural ingredients may work as well, but it depends on how much you want to struggle with it. 

Keep the active ingredients in mind as the most crucial feature of an anti-fungal shampoo.

  • Bottle Size

You want to make sure you have sufficient product to use if you have to keep shampooing your dog. Choose an anti-fungal shampoo that has more than enough product: it’s better to have extra than run out when your dog needs it most.

  • Moisturizing Properties

Choosing an anti-fungal shampoo that won’t dry out your dog’s skin is a challenge, especially since you want his skin to be as dry as possible to prevent the yeast infection from worsening. Specifically, look for anti-fungal shampoos that have a moisturizing agent, especially if your dog has sensitive skin. 

Retaining moisture while treating a yeast infection can be a challenge, but it is possible with the right balance of ingredients.

  • Scents & Perfumes

Most dog shampoos have a pleasant scent that will linger on your dog’s coat after washing. When it comes to anti-fungal shampoos, certain ingredients may create harsh medicinal smells. It may be beneficial to choose a shampoo that has a scent to cover this medicinal smell, however, you need to ask yourself if it’s worth it to expose your dog to harsh perfumes for your own benefit. 

Be careful when choosing a shampoo that’s heavily scented. Dogs with fungal infections may already have sensitive skin, and some fragrances (especially those with artificial perfumes) can irritate them further. Also, be wary of shampoos with a scent that is too strong. You’ll be smelling it for a while. Your dog may also not like the stronger scents, so keep that in mind. 

  • Other Uses

What else are these types of shampoo used for? Anti-fungal shampoos may have various other uses, from deodorizing properties to antibacterial medications and flea and tick deterrents. If your dog has any of these conditions in addition to a fungal infection, choose a shampoo that will address all of them. 

However, if your dog doesn’t have fleas or ticks, avoid getting an anti-fungal shampoo that treats them. This is true of all other uses and different conditions. Get what your dogs need, but avoid getting additional treatments as they may disrupt the healing process. 

  • Harmful Ingredients

You may have seen shampoos that advertise that they are paraben-free or sulfate-free. Why is that a good thing? Parabens, sulfates, phthalates, certain soaps, detergents, and other ingredients can be harmful to your dog. While it isn’t a guaranteed thing, some of these ingredients can cause cancers, aggravate hormone conditions, or further irritate your dog’s skin. 

Target Species

While all of these shampoos can be used on dogs, it’s worth looking for a shampoo that works on cats and other pets as well. If your cat, horse, or ferret comes down with a fungal infection sometime in the future, having a shampoo that works for them as well as for your dog can be extremely beneficial. 

Be careful of using ketoconazole with cats for the reasons mentioned above. Otherwise, look for shampoos that precisely determine a target species list.
