The 5 Best Antifungal Antibacterial Dog Shampoos in 2022 (Review and Buyer’s Guide)

Our dogs love to stick their nose into anything and everything they can find, from sniffing some plants to rolling in the mud. While this is endearing, it can also be frustrating too. God only knows how many diseases they have contracted there.

One of the most common conditions that your dog can catch outside is a skin infection that can be caused by fungus or bacteria. If your furry buddy is intensely scratching, chewing their skin, or pawing at their ears, then that could be a sign of bacterial and fungal infection.

Fungal Skin Infection in Dogs

Although it is not the only type of fungal infection, yeast infection is the most common found in dogs. This infection is caused by the fungus Malassezia pachydermatis, typically found in your dog’s skin and ears together with other innumerable bacteria and fungi.

Under normal conditions, these organisms do not possess any threat to your furry friend and stay dormant most of the time.

However, when your canine’s immune system is compromised — due to allergies or illness — your dog’s skin condition (hot and humid) becomes a thriving environment for the yeast to grow.

Other factors that may contribute to the spurt of yeast include:

  • Warm and damp climate.
  • High-sugar and high-fructose food.
  • Hormonal disorders.
  • Fleas.
  • Steroids or antibiotics.
  • Chemotherapeutic drugs.
  • External skin parasites.
  • Excessive skin folds.

The yeast then begins to reproduce massively out of control, leading to a yeast infection in your dog’s skin. In some dogs with a poor immune system, the yeast infection can escalate rapidly to a chronic condition.

Because this yeast infection is not contagious, your canine won’t get it from another dog. Still, some breeds are more susceptible to skin fungal infection than others.

What are the Signs of a Yeast Infection?

Yeast infection symptoms are clearly visible in the moist areas of skin such as the ears and armpits. Some of the most common signs are:

  • Itchy skin.
  • Reddish-brown, yellow, or bloody ear discharge.
  • Greasy, smelly coat.
  • Red, irritated skin.
  • Scales and crusty skin on the ear flap.
  • Hair loss around the ear.
  • Head-shaking or tilting.
  • Ear scratching or shaking.
  • Thickened skin.
  • Loss of balance.
  • Loss of hearing.

How to Treat Yeast Infection in Dogs

A yeast infection in the dog’s skin and coat can be treated easily using a topical treatment, such as antifungal dog shampoos. If the condition persists, your vet may prescribe something stronger.

If you prefer a natural remedy, you can mix apple vinegar and vinegar water and spray the solution to the affected area. Wait until the skin dries, then cover the area with a thin layer of coconut oil. Repeat the treatment every day until the yeast is gone.

During and after treatment, you have to make sure to dry your furry friend thoroughly after a bath with towels or hair dryer to prevent the recurrence of yeast infections.

To treat yeast infection in a dog’s ears, you’ll have to bring your four-legged friend to the vet. Your vet will then take a look at your canine’s ear canal using an otoscope to determine the cause of infection.

For yeast infection found in the outer ear canal, your vet will be most likely prescribe a topical antifungal ointment. If the infection is located in the middle area, your vet might use tablets or injections. In some cases, surgery may be needed.

Fungal and Bacterial Infections in Dogs

Besides fungus infection, dog skin infection can also be caused by bacteria or a combination of both bacteria and fungal.

There are different types of bacterial and fungal infections in dogs; the most common one is pyoderma. Pyoderma happens when your dog’s skin is disrupted through a wound, scrape, flea bite, or other irritation.

Because of the itchiness, your furry friend will scratch or chew the wounded area, causing an imbalance in the immune system, which makes the bacteria to overgrow.

Most dogs suffering from yeast, due to the similar underlying cause, will most likely develop bacterial and fungal infections. Wrinkly dog breeds, dogs with endocrine issues or allergies have a higher risk of developing a skin bacterial or fungal infection as well.

How to Treat Bacterial Skin Infection in Dogs

The treatment of bacterial skin infection in dogs involves cleaning the affected area (including having the hair clipped), giving topical medications and oral antibiotics. Topical antibacterial dog shampoo can help clean the skin better.

How to Prevent Yeast and Bacterial Skin Infection in Dogs

Managing the cause is the key to prevent the dog skin infection from flaring up.

For example, if your furry buddy has allergies, keeping those allergies under control will reduce the number of skin infections they get. The best treatment plan includes over-the-counter or prescription medication and a diet change.

If your furry buddy often gets flea, you might want to try different prescription flea and tick prevention and shampoo. For dogs with skin folds like Bulldogs, you need to clean those areas daily using a clean, damp cloth.

What To Look For When Picking an Antifungal and Antibacterial Dog Shampoo?

Many antifungal shampoos nowadays include an antibacterial formula, which is a bonus for you as you don’t need to buy separate shampoo.

Here are a few things you want to look for when buying antifungal shampoos for your dog:

  • Ingredients – Look for a shampoo with active ingredients like Miconazole nitrate , Ketoconazole, or Selenium sulfide. Those ingredients are useful for treating fungal infections and other parasitic infections.
  • Chemicals – The shampoo must be from harmful chemicals such as paraben, dye, and soap.
  • Soothing properties – Skin infections cause itching. Therefore, you may want to look for a shampoo that has soothing agents in it, such as aloe vera, tea tree, coconut oil, and palm oil.
  • Natural – Most ingredients in the shampoo should be derived from a natural source.
  • Moisturizer – The moisturizer in the shampoo helps a dry scalp, tames stubborn and unruly hair, and smoothes the coat.
  • Deodorizer – In addition to moisturizer, you might want to look for a dog shampoo that contains deodorizers to keep your canine’s fur odor-free.
  • Fragrance – Artificial fragrances can make your dog’s skin problem worse, so avoid shampoo that contains artificial fragrance. Look for a shampoo that contains natural oils and extracts instead.

Natural Remedies for Dog Skin Problems

These at-home remedies can be used to give your canine some natural relief in addition to the antifungal dog shampoos.

1. 50/50 Apple Cider Vinegar Water Spray

The solution made from a 50-50 mixture of apple cider vinegar and water spray is beneficial to relieve many skin problems such as dry, itchy skin. Moreover, apple cider vinegar has antifungal and antiseptic properties.

2. Coconut Oil

Not only does coconut oil contain antifungal and bacterial properties, but it is also an excellent moisturizer too. Coconut oil can be used to combat fungal or bacterial infections, allergies, eczema, and insect bites. How to use it: massage the oil into the affected area for quick relief.

3. Chamomile and Herbal Tea Soaks

Chamomile has cooling agents, which can help soothe and cool irritated skin, and reduce inflammation. To use this solution, fill up your tub with warm water, take several herbal tea bags, and steep them into it for several minutes. Take the bags, and soak your canine in the water.

4. Oatmeal

Oatmeal is an active ingredient that soothes dry, itchy skin, and fights irritation. How to use: grind plain oatmeal and sprinkle the powder into a warm bath. Then, let your canine soak in the tub for ten to fifteen minutes.

5. Plain, Sugar-Free Yogurt

Some fungal or bacterial infections come from digestive problems and inadequate nutrient absorption. Feeding one teaspoon (for puppies) or two teaspoons (for adult dogs) of plain, sugar-free yogurt will improve your dog’s overall gut health and digestion.

How to Bathe a Dog with Yeast or Bacterial Infections

  1. Once you find the dog shampoo that you like, read the direction on the shampoo first. It’s a good idea at first to test the shampoo on a small patch of skin just to make sure your dog is alright.
  2. Pour water over your furry buddy. Don’t submerge your canine in hot or warm water unless directed to do to avoid aggravating the yeast.
  3. Apply the shampoo all over your dog’s body and let it sit for at least 10 minutes.
  4. Apply the shampoo on a washcloth and wash your dog’s face. Make sure to be careful around areas like eyes, nose, mouth, and ears.
  5. Rinse your dog entirely following the directions on the shampoo. Pat dry your dog with a clean towel, be careful not to rub the affected skin. Then air-dry your dog using a blow dryer on a cool setting.
  6. Use the shampoo twice a week at first to put your furry buddy on the path to recovery.
