Your dog's skin is her first line of defense against germs and contaminants from the outside world. Infections of the skin can lead to deeper infections if they leech into a dog's bloodstream and begin attacking the body from the inside.

Always keep the best dog skin infection treatment in your canine first aid kit for use at the first signs of infection.

Seek your veterinarian's help if your dog contracts a skin infection. They will certainly know the suitable, safe antibiotics for dog's skin.

While it may look like a little spot on a dog's skin, skin infections in dogs are a serious matter and the smallest skin infection can spread quickly.

Dog Skin Infection Treatments

Beginning signs of a dog skin infection include:

  • redness
  • bumps on the skin
  • open sores
  • constant licking or scratching of the infected area
  • shaking of the head or scratching of the ears

Dog skin infections can be caused by a fungus (like yeast), bacteria, or parasites. There may be an underlying cause like allergies.

For example, if your dog has itchy skin and scratching due to allergies, this will cause an open sore or wound on the skin that will later become infected.

Using a skin infection treatment for dogs is an effective way to prevent more serious issues. At times, your vet will recommend dog antibiotics for skin infection.

Below, we discuss more on what you need to know about these treatments, as well as review and rank the best dog skin infection treatment available over the counter:

How to Treat Skin Infections in Dogs

How to Treat Skin Infections in Dogs like demodicosis in dogsThere are several causes and dog skin infection types, but majority of products will work regardless of the exact reason.

Your vet should always be the first source on what best dog skin infection treatment to use and how to use it.

Before you pick the product, figure out your dog's skin condition and reason for infections. The last thing you want to happen is for your dog to have a bad reaction to an over-the-counter antibiotic cream for dogs.

Skin infections in dogs that come with itching are caused by fleas in most cases (and, subsequently, dog flea dermatitis allergy).

As well as atopic dermatitis, staph, parasites, Demodex mites (mange, or other mites in dogs).

Sarcoptes mites (or scabies in dogs), allergies, and, finally, bacteria, which is a result of a pet having any mentioned dog skin conditions.

Best dog skin infection treatment products will treat the majority of these skin infections in dogs but in different ways.

For instance, some dog infection medicine will only heal the external scarring but not really whatever is wrong on the inside.

You can pick between dog shampoo, spray, liquid solution, wipes or ointment.

What you choose depends on how and where you're going to use it, and the type of dog skin infection your pet has.

Rule Out Internal Causes of Your Dog's Skin Condition

Consider if the reason your dog is itching is due to a more serious health condition that may need a very specific treatment.

Dog skin conditions and problems can be caused by serious diseases like cancer, Cushing's disease, autoimmune disease, hyperthyroidism or hormone imbalances in the canine's body.

While they usually do not cause itching in dogs, they may be interrelated with the above-mentioned skin infections in dogs.

“As there are numerous causes of skin lesions in dogs, it is important to determine the underlying cause to help guide treatment recommendations.”
– Dr. Alison Diesel, DVM [source]

This is why it's important to seek veterinary care quickly.

You can use the best dog skin infection treatment products while you're waiting to get an appointment.

But your vet will give your dog a thorough examination to see if there is any underlying conditions that lead to these dog skin conditions in the first place.

Why and When to Use Over the Counter Dog Skin Infection Treatments?

The reason many pet owners choose to use some of the best OTC dog skin infection treatments is that more and more dogs are becoming resistant to prescription antibiotic treatments that veterinarians prescribe.

Due to overuse, the bacteria has become immune to these treatments, and some over-the-counter products work better.

According to new research, veterinarians now often recommend using topical treatments for skin infections in dogs instead of expensive, prescription-based antibiotics.

“Although we’re used to thinking of topical products as adjunct treatments used in addition to antibiotics, that thinking has changed, and dermatologists are now advocating that topicals be used instead of antibiotics wherever possible”
– Dr. Douglas J. DeBoer, DVM [source]

While topical treatments like the ones mentioned below – ointments, sprays, and liquid solutions among the best dog skin infection treatments – should be the first step towards battling skin infections in dogs.

It's also recommended to combine several options, such as using antiseptic wipes and bathing a dog with antibacterial shampoo (like the Curaseb one, for example) to treat these infections more effectively and quickly.

Bathing Your Pooch with Dog Skin Infection Treatments

Skin infections in dogsSome pet owners are worried that bathing dogs with skin infections will dry out their skin and cause more problems, but that is a misconception and it was never true.

Weekly, and in some cases, daily baths are still recommended for dogs with skin infections.

These baths will rid your dog of possible causes of skin infections like bacteria, allergens, and other agents (e.g. yeast and mites).

Your veterinarian will recommend the exact bathing schedule based on the exact cause of a dog's skin condition.

Occasional baths during a week, paired with topical treatments like an antimicrobial spray or medicated solution have been observed to be very effective.

Such as in the 2015 study by Olivry where it was demonstrated how combined treatment works best for dog dermatitis.

“We know that bathing removes allergens and infectious agents like bacteria and yeast, and helps restore epidermal function in humans. Can it do the same in dogs? It’s a bit unclear, but I’ve observed it helps a lot with my atopic patients. Some can even be controlled that way alone.”
– Dr. John Plant, DVM [source]

If your pet is dealing with a skin condition, consult with your own veterinarian, get one of the best dog skin infection treatments, and preferably several different types.

Every case will vary, and dog antibiotics for skin infection may end up more effective for your pooch. So, this shouldn't fully rule out antibiotics for dog's skin.

Let your vet make a thorough examination and develop a treatment plan of how you're going to tackle this on your dogs.

Always use the products as directed and as advised by your veterinarian.

The first on the list of best dog skin infection treatment products is a brand that's already established itself as the top product for ear infection treatments for dogs.

Pet King Brands’ Zymox Pet Spray with 1% Hydrocortisone contains the patented naturally-derived LP3 Enzyme system of Zymox which is a technology that destroys bacteria, fungus, and many viruses.

No prior cleaning to the affected area is required in its application.

The addition of hydrocortisone reduces inflammation of affected areas.

What Makes It a Recommended Dog Skin Infection Medicine

This is because it contains hydrocortisone, which works on skin problems of various origins, not just viral, bacterial, or fungal. It works fast, too.

Skin that’s raw from intense scratching will generally dry up in days, there will be an almost instant relief from itching, paw-chewing will stop in a matter of hours.

And infections and breakouts will clear up in a week or less.

You may have noticed that this dog skin infection treatment comes in a very small bottle, so while it’s pretty effective, it’s very expensive, too.

Active Ingredient: Hydrocortisone 0.5%.
Other Ingredients: Aloe vera, benzoic acid, benzyl alcohol, dipropylene glycol, glucose oxidase, glycerin, isopropyl myristate, lactoferrin, lactoperoxidase, lysozyme, potssium iodide, propylene, glycol, purified water, sodium benzoate, tripropylene glycol, zinc gluconate.

It’s simply topically applied on the affected area and reapplied after 3 days until the affected area completely heals.

What Makes It The Best Dog Skin Infection Treatment

Possibly one advantage of Pierce's Nu-Stock Ointment over others is its wide range of applications.

Dog Breeds That Are More Prone to Skin Infections
