Choosing the perfect antifungal shampoo for your furry friend might seem overwhelming with the multitude of options out there. How do you know which one suits your dog best? Should you go for a medicated shampoo or something more natural? Continue reading for a breakdown of what to consider when selecting an antifungal and antibacterial dog shampoo.

Fungal Infections:

Fungal dermatitis is a common woe among dogs, marked by symptoms like intense itching, ear infections, and flaky or crusty skin—particularly in skin folds, nails, armpits, and the anal region. Treating fungal dermatitis often involves antibiotics or topical solutions like shampoos and ointments.

Medicated Ingredients:

Most medicated antibacterial and antifungal dog shampoos contain key ingredients like ketoconazole and chlorhexidine gluconate. Chlorhexidine gluconate prevents bacteria from sticking to the skin by enhancing cell wall permeability, effectively breaking down the walls. 

It’s effective against Gram-negative and Gram-positive bacteria and various fungi, including yeasts. Ketoconazole combats fungi and yeast by creating holes in the cell membrane, causing cell contents to leak and effectively eliminating the infection.

Natural Alternatives:

Several natural ingredients boast antibacterial and antifungal properties, such as lemongrass—an essential oil in natural antibacterial dog shampoos. Lemongrass is a potent alternative with antibacterial properties that target candida and staphylococcus.

Additional Beneficial Ingredients:

When looking for the right dog shampoo, consider aloe vera, oatmeal, ceramides, and shea butter. Combined with active ingredients, these elements combat infections and soothe, moisturize, and relieve your dog’s itchy skin.

Steer Clear of Harmful Chemicals:

While seeking beneficial ingredients, be wary of the harmful ones commonly found in dog shampoos. Avoid parabens, formaldehyde, propylene glycol, cocamidopropyl betaine, ammonium, and sodium benzoate. These substances can pose serious health risks to your furry friend.

How To Choose the Right Antibacterial Shampoo for Dogs?

As the dog’s owner, it is your job to pick the products used on them.

You want high-quality dog products to increase your dog’s lifespan and quality of life. 

Check out the ways to choose the right antibacterial shampoo for dogs below.

What Ingredients Should Not Be in an Antifungal Dog Shampoo?

While some great products are on the market for treating your dogs’ skin infections, many companies take shortcuts and add toxic ingredients to their shampoo. 

These ingredients cause harm to your dog. 

Check out the list of common toxic ingredients found in dog shampoo.

  • Triclosan
  • Petrochemicals
  • Phenoxyethanol
  • Synthetic dyes
  • GMOs
  • Silicones
  • Mineral oils
  • Sulfates
  • Synthetic fragrances
  • PEG and PPG
  • Phthalates
  • Parabens
  • Formaldehyde
  • Isopropyl alcohol
  • Cocamide MEA
  • Ethanolamine compounds

If you see any of these ingredients in your dog’s shampoo, you want to get a new shampoo.

You want to avoid these ingredients because they are toxic to dogs. 

Look for natural colors and fragrances.

Know Your Dog’s Allergies

Every dog is different. One shampoo may work wonders for your neighbor’s dog but make your dog break out. Just like humans, dogs benefit best from products made for them.

Allergy tests can be done to know what your dog is allergic to.

If you do not want to spend the money on a test, pay close attention to how your dog reacts to certain shampoos.

This concept can be used when choosing dog food, too. If your dog seems to have more skin issues or stomach issues after changing its food, they are most likely allergic to something in the food.

Many skin irritations in dogs start with their food, so ensure you get high-quality food to decrease the possibility of a food allergy. Use this same concept when choosing a dog shampoo. Pay attention to the way your dog reacts to the shampoo you choose.

If they break out or become more irritated, try a different shampoo with active ingredients.

Beneficial Ingredients

There are a lot of bad ingredients in dog shampoo, but there are some great ones, too. 

Some ingredients to look for when choosing your dog shampoo include aloe vera, oatmeal, and shea butter.

All of these ingredients are soothing for the dogs’ skin. Active ingredients like ketoconazole and chlorhexidine gluconate will kill or inhibit the bacteria and fungus, while the rest should soothe the skin. 

Also, natural ingredients like lemongrass essential oil are a great natural alternative for treating infections. 

Is Anti-Fungal Shampoo Safe for Dogs?

Yes, antifungal shampoo is safe for dogs.

Antifungal shampoos should be used on dogs suffering from fungal skin infections. 

These shampoos can help treat and soothe dogs so they no longer suffer.

How Fast Does Antifungal Shampoo Help Yeast on a Dog?

Antifungal shampoo must contact the dogs’ skin for at least five to ten minutes to be effective.

Repeat baths every three to five days for two to twelve weeks. You don’t want to stop using your antifungal shampoo too soon. 

If you stop using the medicated shampoo, the least susceptible fungi that survived the first round will continue reproducing, resulting in an even stronger fungus colony on your dog’s skin.

How Often Should Dogs Be Bathed With Antifungal Shampoo?

If your dog has a fungal infection, they should be bathed weekly with an antifungal shampoo.

You do not want to stop using your antifungal shampoo too soon.

Ensure your dog’s fungal infection is gone before stopping their weekly baths.

Fungal infections can take weeks to clear up. But once the infection is cleared up, how often you should bathe your dog with regular shampoo will depend on several factors, including their coat type.

For example, dogs with thick double-layer coats, like German Shepherds, should only be bathed every 4-5 months

Bathing these dogs too frequently will increase the risk of damaging the protective oils on their coats. 

This will lead to an increased risk of developing a skin infection. That is why it’s so important to pay attention to your dog’s breed characteristics to choose the best solution for their long-term health.

What Conditions Can and Can’t an Antifungal Dog Shampoo Help?

Antifungal shampoo is a great way to combat many fungal infections in dogs.

However, antifungal shampoo cannot cure everything. 

Antifungal shampoo is great for treating infections like fungal dermatitis and ringworm.

These are common fungal infections that medicated antifungal dog shampoo can treat.

Aspergillus is a mold fungus commonly found in the environment. If this fungus gets on your dog and causes irritation, the antifungal shampoo will not help. This fungus resists fluconazole, a drug commonly used to treat molds and other fungi.

Does Antifungal Waterless “Dry” Shampoo Work?

There are mixed feelings about waterless antifungal shampoo. While it can help reduce fungal infections, these shampoos do not work as well, as regular shampoo needs water to work the best. 

How Does Antifungal Dog Shampoo Work?

Antifungal dog shampoos are packed with antifungal ingredients that either kill or prevent the reproduction of fungus on your dog’s skin and coat.

Some medications cause holes in the cell wall of the fungus. These holes either let essential components of the fungus fall out of the cell or allow surrounding cells to invade the fungus cell.

Both of these situations cause the fungus to die. As the fungus dies, the dogs’ skin becomes more healthy.

Thus, soothing ingredients like aloe vera and oatmeal come to the rescue to help moisturize and heal the abrasions on the dog.

Can Dogs Get Fungal Infections?

Yes, dogs can get fungal infections. Fungal infections affect both the interior and exterior of the dog. Skin fungal infections that affect dogs include dermatitis and ringworm.

Interior fungal infections that affect dogs include blastomycosis and cryptococcosis. Interior infections cannot be treated with an antifungal shampoo.

How Do You Treat Fungal Infections in Dogs?

Fungal infections in dogs can be treated in multiple ways. Topical treatments include medicated mousse and medicated antifungal shampoos. For internal fungal infections, drugs are ingested to treat the fungal infection.

Does Antibacterial Shampoo Work on Dogs?

Yes, antibacterial shampoo does work on dogs. It must be used frequently to clear up the fungal infection.

When To Use Antibacterial Shampoos for Dogs?

Antibacterial shampoo should be used on dogs when they suffer from bacterial infections, like hot spots or staph infections.

What Can I Bathe My Dog With for a Yeast Infection?

Bathe your dog in medicated antifungal shampoo to clear up yeast infection.


In conclusion, selecting the right antibacterial and antifungal dog shampoo is crucial for maintaining the skin health of your furry companion. The variety of options available, each with unique benefits, ensures you can find the perfect fit for your dog’s needs. 

Whether opting for natural alternatives or medicated solutions, prioritizing ingredients, avoiding harmful chemicals, and considering your dog’s individual sensitivities are essential steps. The comprehensive list of the seven best shampoos provides a valuable guide to help you make an informed decision, ensuring your loyal friend enjoys a clean, healthy, and itch-free coat.
