How Does Medicated Dog Shampoo for Allergies Help?

Many dog shampoos claim they can fight allergies, but you have to look at the ingredients list—some ingredients help more than others. And of course, look for a medicated dog shampoo.

Shampoos for allergies serve one of two functions. They can reduce symptoms that trigger skin allergies. Or they can improve your dog’s resistance to the allergen. Most of the shampoos contain only natural ingredients. Tea tree oil, aloe vera, oatmeal—those are the ingredients you want.

Dog Breeds Prone to Allergies

We mentioned before that some breeds are more prone to allergies than others. This might come as a surprise, but many of the popular breeds are prone to allergies.

For example, the Golden Retriever is one of the most popular breeds, and they are often affected by allergies. They can get hot spots from licking and chewing their itchy skin. Golden retrievers have floppy ears, so they are prone to ear infections as well.

The Labrador is another popular dog breed. He is more prone to seasonal allergies, and in some cases, their allergies last throughout the entire year.

The German Shepherd is a great companion dog. But over the years, their health has declined, which is why they are more prone to allergies than before.

You can find the full list of dogs prone to allergies here. There are many more breeds, like the Bichon Frise, the Boxer, Cocker Spaniel, and others.

Types and causes of allergies

Allergies are a misguided reaction to foreign substances by the immune system. Just as in humans, there are different types and causes of allergies. Let’s take a look.

Skin allergies

This is the most common type of canine allergy. You can protect your dog from skin allergies with the best dog shampoo for itching allergies. Itching allergies fall into three groups: environmental allergies, flea allergy dermatitis, and food allergies.

Yes, even food allergies can cause itchy skin. Now, you can’t prevent food allergies with a shampoo—you need to change your dog’s diet for that. Environmental allergies involve dust, pollen, and mold, all of which can cause an atopic allergic reaction.

Flea allergy dermatitis is a reaction to fleabites. Some dogs can be allergic to flea saliva; they become itchy and their skin becomes inflamed. You can notice excessive itching at the base of the tail.

Food allergies

You have to make a distinction here. There are food allergies that cause an immune response and gastrointestinal signs. And there are food allergies that result in skin issues.

Dogs can have food sensitivity as well. Or food intolerance. Food sensitivity does not involve an immune response. Rather, they display a gradual reaction to an ingredient in the food. Dogs with food sensitivities can show symptoms like vomiting and diarrhea.

Acute allergic reactions

Acute allergic reactions can be life-threatening. Your dog might go into anaphylactic shock. They can have a severe reaction to an allergen. This type of allergy happens due to bee stings and vaccine reactions. This is why vets recommend keeping a close eye to your dog 24 hours following a vaccination.

Symptoms of allergies in dogs

The most common symptom is the itching of the skin. This can happen in one area or all over the body. In some cases, symptoms can include respiratory issues as well. Coughing and sneezing are common. Here is a full list of symptoms your dog might display:

  • Itchiness
  • Hives
  • Swelling
  • Red and inflamed skin
  • Vomiting
  • Diarrhea
  • Sneezing
  • Itchy ears
  • Itchy eyes
  • Constant licking

Diagnosing allergies in dogs

Diagnosing allergies is a complicated business. Allergy tests are not always 100% accurate. If you suspect an allergy, take your dog to the vet.

There, the vet will try to determine the conditions causing the allergy symptoms. Your vet will recommend allergy testing. But food allergies are tricky, and an elimination diet works the best for diagnosing a food allergy.

How common are allergies in dogs?

The bad news is that allergies are common in dogs. They can affect dogs of all breeds and backgrounds. Some experts might tell you that mutts are less likely to develop an allergy. Yes, that’s true. Pure breed dogs are more prone to allergies. But that doesn’t have to be the case.

Allergies can appear after six months of age. Most dogs show symptoms when they are one or two years old.

Dogs can inherit some allergies. Allergies to pollen and plants, for example, fall into the inherited allergy group.

Homemade solution for dog shampoo

There are many homemade solutions for the best dog shampoo for allergies. For example, you can opt for a homemade dog shampoo with coconut oil. Others prefer homemade dog oatmeal shampoo.

Our pick is vinegar. This solution helps with fleas and irritation, but it also reduces dog odor. Your pet will be clean and smell fresh.

For this homemade shampoo, you need 1 quart of water, 1 cup of vinegar, and 1 cup of baby shampoo. You can use white vinegar or apple cider vinegar. And you can substitute baby shampoo with any non-toxic dish soap.

Apply the solution with a spray bottle. Massage it well into his fur. Apply to the hard-to-reach areas, like down the chest and under the forearms. Let it soak for five minutes, and then rinse.

Buying Guide

There are a couple of factors to consider when looking for the best dog shampoo for allergies. You need a shampoo that is free of harsh chemicals. There should be no parabens, sulfates, or soaps.

You want ingredients that help with the condition. For example, the best anti-itch shampoo for dogs should contain oatmeal and aloe vera, which help soothe itchy skin. Another positive is you can use them more often. Natural ingredients are a must. Tea tree oil works well too, because it helps heal irritated skin.

Last, but not least, look for pH-balanced shampoos. Your dog has a different pH than humans, and you must respect that.

All shampoos on our list are gentle on the skin, contain helpful ingredients, and lock in moisture.


There is no one best shampoo for dogs with allergies. The shampoo that works for you might not work for your friend. Dogs can be allergic to many things. There are also environmental and other factors to consider.

With all that in mind, we still consider Earthbath to be the best option. The shampoo is hypoallergenic and should tackle the root of the issue. If you need more something potent, Allertech will do the trick. Depending on the severity of the issue, you might need a more potent shampoo.

In any case, make sure to take your dog to the vet to diagnose allergies and find the root cause of the problem.
