Bathing is a necessary evil for dog owners but sometimes bathing your dog is about more than just keeping him clean – sometimes it’s a form of treatment for infections and other skin problems.

Keep reading to learn more about anti-fungal and antibacterial dog shampoos and when they might be needed. You’ll also find our top 6 picks for the best anti-fungal and antibacterial dog shampoos of 2024.

8 Reasons Why Anti-Fungal & Antibacterial Shampoos Are Needed

Most dogs need occasional baths to keep their skin and coat clean. If your dog has a very long or fine coat, more frequent baths may help to keep things neat and tidy. For everyday bathing, a regular dog shampoo will get the job done but if your dog is suffering from a skin infection, he’ll need something a little stronger – he’ll need an anti-fungal or antibacterial dog shampoo.

Here are the top 8 reasons why your dog might need an anti-fungal or antibacterial shampoo:

  1. Intense itching, licking, or biting at the skin.
  2. Irritation or inflammation in moist areas of skin (ears, paws, armpits, and skin folds).
  3. Shaking the head, pawing at the ears, or tilting head to one side.
  4. Brown, waxy discharge from the ears, often with a foul odor.
  5. Greasy coat and smelly or oily skin.
  6. Ring-shaped patches of red, irritated skin.
  7. Scaly, crusty skin, often with patches of dryness and hair loss.
  8. Papules or pustules on the surface of the skin, sometimes with pus or discharge.

All of the problems above point to a problem affecting your dog’s skin. In most cases, these symptoms are related to either a yeast (fungal) infection or a bacterial skin infection.

Anti-fungal dog shampoos are a common form of treatment for yeast infections. Yeast infections in dogs are caused by an overgrowth of Malassezi bacteria. These bacteria are normally present in your dog’s ears and skin, but it doesn’t cause a problem until something causes a shift. When your dog’s immune system becomes compromised, when his ears stay too wet for too long, or when the environment becomes particularly hot and humid, these bacteria can multiply rapidly and cause a skin infection.

Symptoms of yeast infections in dogs include intense itching, irritation and inflammation of the skin, redness or sores, and a sticky discharge. These symptoms are most commonly seen in moist areas of skin such as the ears, armpits, between the toes, in the nose, and in folds of skin. Some dogs also develop a greasy coat, foul-smelling skin, and a yellow/green discharge. Medicated Anti-fungal dog shampoos can help clear up the infection to restore balance and heal the skin.

Another common fungal infection seen in dogs is ringworm. Though the name might suggest otherwise, this condition has nothing to do with worms and everything to do with fungi called dermatophytes. Ringworm causes ring-shaped skin lesions and may be accompanied by itching and redness. Anti-fungal dog shampoo for ringworm can help resolve the infection and heal the skin.

If your dog developed dry, scaly, or crusty skin, a bacterial skin infection is more likely to be the problem. These infections can also cause patches of hair loss, the development of pustules or papules, and pus or discharge from the skin. Bacterial skin infections in dogs are commonly caused by allergies (contact or inhalant allergies, food allergies, or flea bite allergies), hormonal imbalance, liver disease, kidney disease, and various immune disorders. Antibacterial shampoos can help kill the bacteria, giving the skin a chance to heal.

What to Look for in a Top-Rated Anti-Fungal & Antibacterial Shampoo

Before you start shopping for anti-fungal or antibacterial dog shampoo, you need to take your dog to the vet. Many skin problems present with similar symptoms and you don’t want to make an incorrect assumption about what’s really going on. Your vet will be able to diagnose your dog’s skin problem as fungal or bacterial, at which point you can then start shopping for the right shampoo.

Here are some things to look for when shopping for anti-fungal and antibacterial dog shampoo:

  • Medication – While a regular dog shampoo might contain ingredients to soothe and moisturize your dog’s skin, if he has an infection, you’ll need a shampoo with an anti-fungal or antibacterial component. Keep in mind that some medicated shampoos will contain both.
  • Active Ingredients – In addition to making sure that the shampoo has active ingredients to deal with fungal and bacterial infections, you should check the concentration. Ask your vet for recommendations about specific agents and concentrations to look for.
  • Moisturizer – Not only do you want a medicated shampoo that will clear up your dog’s skin infection, but you also want to choose one with moisturizers to help repair and heal the skin.
  • Cooling Agents – Soothing ingredients like aloe vera can help cool your dog’s skin down, reducing inflammation and supporting the healing process.
  • Deodorizers – Many dogs with skin infections develop a foul odor, so choosing a shampoo that contains deodorizing agents may be beneficial.
  • Essential Oils – A component of many natural dog shampoos, essential oils offer natural antifungal and antibacterial benefits in addition to natural scents.
  • Fragrances – Because there is a high risk of making your dog’s skin problems worse, you should avoid shampoos that contain artificial fragrances. Look for products scented with natural oils and extracts instead.
  • Chemicals – Though you want to make sure the medicated shampoo you choose contains active ingredients to fight fungal and bacterial infections, you should avoid products made with too many other chemicals.

In addition to the things listed above, there are a few other things to think about when comparing products. For example, check how often the shampoo needs to be applied and how long you need to wait between treatments. You should also make sure that the shampoo is safe for puppies or very small dogs if your pup fits into either of these categories.

Does vinegar kill yeast on dogs? – Vinegar is a natural remedy for yeast infections in dogs, but it is best used in combination with an anti-fungal dog shampoo. Once you use the shampoo to remove the waxy buildup and accumulation of yeast in your dog’s skin and coat, you can treat him with vinegar to take care of what remains. Apple cider vinegar works well, and it has natural healing properties as well. Mix equal parts water and apple cider vinegar then spray it on the affected area and let dry.

  • Can I use antibacterial soap on my dog? – Antibacterial soap can be used to kill bacteria and other microbes which could be causing an infection in your dog’s skin. Compared to regular soap or dog shampoo, antibacterial soap kills more pathogens but it can also kill off beneficial bacteria in some cases. When used on occasion, it may be safe for dogs but if your dog has a bacterial skin infection you are better off using a medicated antibacterial shampoo formulated for dogs.
  • How can I treat my dog’s yeast infection at home? – If your dog has a widespread yeast infection, one way to treat it is with a 50/50 solution of apple cider vinegar and water. Spray the affected area or soak a clean cloth in the mixture and wring it out before applying it by hand. Once the skin dries, cover the area with a thin layer of coconut oil. Repeat the treatment every 24 to 48 hours until the problem is resolved.
  • What is a natural cure for dog fungus? – Yeast infections caused by fungus can be treated with several natural ingredients. Spraying a 50/50 mix of hydrogen peroxide and apple cider vinegar on the affected area can help kill the yeast and resolve the infection. Let the mixture sit for 15 minutes then wipe clean with a damp cloth. Finish with a thin layer of coconut oil to keep your dog’s skin moisturized and protected.

The right anti-fungal or antibacterial dog shampoo could solve your dog’s skin problems almost overnight.
