By nature, dogs tend to get into everything they shouldn’t. 🙂

While this is endearing it’s also the reason they can easily develop skin infections and catch certain diseases from time to time.

Depending on what your dog contracted and how it’s presenting, there are different treatments including the use of antibacterial dog shampoo.

If you’re unfamiliar with this type of product, here you’ll find information on it along with some of the best antibacterial dog shampoos currently on the market.

What Causes Infections in Dogs?

1. causes

Before learning about the treatment, it’s important to understand what causes common infections in dogs.

Skin infections are the most common forms of infection your pup can contract. The most common causes for a skin infection are :

  • Predisposition to allergies
  • Constant licking and scratching
  • Floppy ears trapping dirt and moisture
  • Natural skin folds trapping dirt and moisture

In general, allergies play a large role in bacterial infections due to the itching, licking, and biting that occurs while your pup attempts to soothe themselves.

As your dog does those things, they can easily break the skin allowing dirt to settle in and cause an infection.

That being said, any dog at any time can contract a skin infection despite none of the above being present.

For example, an infection could be linked to a parasitic infestation, an alien object they ingested, or a ruptured eardrum.

For this reason, it’s always best to take your dog to a veterinarian if you suspect something is wrong. They’ll be able to give you a specific diagnosis and treatment plan to help your furry friend feel better.

Benefits of Antibacterial Dog Shampoos

2. benefits

While any form of treatment will be beneficial for your sick pup, there are specific benefits linked to antibacterial dog shampoo.

Some of these benefits are :

  • Can be made specifically for certain conditions
  • Provide closer-to-immediate relief for most dogs
  • Manufactured by trusted companies
  • Regulated and monitored by a governing body

Cleaning the affected area

When your dog has a bacterial skin infection, the affected area needs to be cleaned as soon as possible. If your dog has a lot of hair, that restricts the entry to the affected area, clip the hair.

Use topical anti-bacterial shampoo in these areas. Sometimes baths may be needed up to two times a week in conjunction with the antibiotic medicine that your dog might be taking.

Kill bacteria

This is the most important part of the treatment.

The medicines are already doing this but shampoos help in killing bacteria from the fur and skin and preventing them from coming back soon.

Soothing and medicated shampoos which are for topical, anti-bacterial use can be applied. You can use them as much as 2-3 times a day for best results and speedy recovery.

Although before taking these steps on your own we would recommend that you consult a vet.

Couple all of that with the fact of the matter that an antibacterial dog shampoo can clear up your dog’s infection, and you’ll more than likely agree that medicated shampoos are worth keeping in the house as a pet owner.

How to Spot Infections in Your Dog

3. how to spot

Visible infections, whether bacterial or fungal (yeast), are easy to notice just by looking at your dog.

You’ll likely see the infected areas on your pet’s skin as well as scabs, flaking, skin, and residue on their coat.

Noticeable symptoms like excessive scratching, biting, licking, and head shaking are also common signs of an infection.

Your dog may also have more subtle symptoms that are proof of irritation.

Those can be constant head tilting or rubbing (either with their paws or rubbing their head on things like a couch or carpet), or changes in behavior.

If you’re trying to figure out what’s wrong with your dog, look for common symptoms. The symptoms for a bacterial infection are :

  • Open sores, raised bumps, or pimples
  • Yellow or green discharge from the ears
  • Shaking or constant tilting of the head
  • Scratching and/or rubbing of the ears
  • Excessive licking of the bothersome area
  • Symptoms of a fungal/yeast infection are :
  • Greasy skin accompanied by an odor
  • The yeasty infection usually in moist areas or on the paws
  • Shaking/tilting of the head
  • Scratching of the ears
  • Waxy, brown discharge possible in the ear

While some symptoms occur in both instances, look for accompanying symptoms to narrow it down.

For example, if your dog is scratching their ears a lot, it could be either bacterial or fungal, but if that scratching goes along with them biting their paws constantly, it’s safe to assume a yeast infection.

Remember, go to your vet to get a proper diagnosis before trying to treat the issue on your own.

How to Treat These Bacterial Infections?

4 how to treat

While your vet will work out a whole treatment plan for your furry pal, there are different ways to treat these common kinds of infections. One of the best ways is with medicated dog shampoo.

Anti-bacterial dog shampoo is a medicated shampoo that is made specifically to clear up skin infections.

These can be further narrowed down to specific conditions or they can be general medicated shampoos.

Due to a saturated market, it’s best to try to get something specific to your dog’s needs so you’re not choosing from such a broad range of general anti-bacterial dog shampoos.

What to Consider when Buying Antibacterial Dog Shampoo

5. buying guide

When looking to buy an antibacterial dog shampoo, you have to keep certain things in mind.

You’ll notice that there are a lot of products available but not all are created equal and some are always better than others.

By keeping certain considerations in mind you can narrow down your options easier and find the best antibacterial dog shampoo for you and your canine companion.

What to Look for in the Description

When comparing dog shampoos, you should look for ones that are soap-free, fragrance-free, and paraben-free if possible.

These are all ingredients that can irritate your dog’s skin and possibly make their infection worse.

You may also want to pick a dog shampoo that is hypoallergenic if your dog suffers from allergies frequently.

Consider looking for options with the following ingredients, too :

  • Aloe vera
  • Coconut oil
  • Oatmeal
  • Olive oil
  • Omega-3 Fatty acids
  • Vitamin A
  • Vitamin E

Why Use Natural Antibacterial Dog Shampoos?

6. natural

While medicate dog shampoos tend to have synthetic ingredients or harsh medications in them to help clear up an infection, there are natural antibacterial dog shampoos that use natural ingredients with antibacterial properties to fight back mainly against bacterial and fungal infections.

Usually, they work just as well as the harsher formulas but are less likely to irritate overly sensitive dogs.

In order to be deemed a natural shampoo, there should be no artificial ingredients.

These shampoos are biodegradable and shouldn’t contain things like soap, fragrances, dyes, parabens, or sulfates.

Those types of ingredients can irritate your dog by throwing off their pH levels and preventing their natural oils from conditioning their skin.

The benefits of a natural antibacterial dog shampoo are :

  • Gentle formulas that won’t cause irritation
  • Soothing sensations for itchy skin
  • Ability to balance skin pH naturally
  • Provides relief from allergy symptoms
  • Rids bacteria from the skin and coat

How Frequently and for How Long Do You Use These Shampoos on Dogs?

7 how long to use

In general, you’ll need to use an antibacterial dog shampoo until the infection in question clears up.

If you’re under a vet’s care, they may tell you to bathe your dog with a medicated shampoo two times a week, once a week, or at a similar frequency.

It’s important that you follow those instructions first instead of following other recommendations or the shampoo’s label.

While healthy dogs shouldn’t be bathed too often, frequent bathing in the treatment of skin infections is recommended because it helps clean off scabs and flaking skin that carries bacteria and spread the infection .

It’s also shown that frequent medicated baths help oral antibiotic treatments work better since they help keep the infection localized.

Similarly, your vet will tell you how long you should use the shampoo. Oftentimes, you’ll be told to use the shampoo until the infection is gone, but there are some shampoos that can be used for normal baths even after the infection clears up.

You should take note of any adverse side effects your dog might show and discuss them with your vet.

For example, since some antibacterial dog shampoos can be harsh due to the medication in the formula, it could end up irritating your dog more than it soothes them.

If this happens, your vet might tell you to stop using that particular shampoo and replace it with a gentler one or tell you to reduce the frequency of use (once a week instead of twice a week, for example).

Can Chemicals in Antibacterial Shampoos Harm a Dog’s Skin?

8. can chemicals harm

Since antibacterial dog shampoos are meant to treat infections, they’re generally safe to use, especially the ones prescribed by your vet.

However, unless you’re using an all-natural dog shampoo, there is a chance that the synthetic ingredients in your antibacterial dog shampoo can harm your dog’s skin.

The issue here is that there are no governing regulations for pet grooming products, including antibacterial dog shampoos.

This means that there are no set standards to meet, the manufacturers don’t have to list all of the ingredients, and that there are instances of companies claiming to be natural when they really aren’t.

The only dog shampoos that are governed by any regulating body are certified-organic dog shampoos.

In order to get the designation “certified organic” the shampoo has to meet the FDA’s standards for an organic product.

This means that all of the ingredients must be listed and everything had to meet quality standards in terms of purity and product integrity.

There are no clear-cut studies to prove that chemicals in these shampoos can cause harm to a dog’s skin, but there are reports with all products from users who say their dog had an adverse reaction to a shampoo.

However, for every review that reports skin damage, there are other reviews that claim the shampoo worked perfectly for their pet. So, really, this is more of a case-by-case basis than anything else.

To see how a shampoo affects your dog, start with a patch test.

Use the shampoo on a small part of your dog (preferably an area without visible irritation) and see if they react poorly to it. Look for new irritation like redness, raised bumps, and burns.

Continue to monitor your dog for an hour or so after the patch test and see if they’re scratching or licking the tested area.

If any of this occurs, your dog is having a bad reaction to the shampoo and you should discontinue it.
