Last Updated on December 16, 2021 by Dogs Vets

Starting from the beginning, here are 5 reasons why your dog itch.



Your dog might be scratching and itching more than usual and you might not know why. Your dog could be trying to get rid of skin parasites, fleas, or a yeast infection. The top five causes for your dog’s itching are listed here.

  • Fleas
  • Skin parasites
  • Yeast infection
  • Environmental allergies
  • Insect bites

Dog Allergies and Skin Issues Explained

Dogs can experience allergies and skin issues too. For example, there are a lot of dogs out there that are allergic to fleas and suffer from itchy skin. With proper treatment, these symptoms can be managed.

Dog Allergies:

  • An allergic reaction to a dog’s natural skin cells or dander (tiny scales)
  • Allergic reactions may vary from skin redness, itching, scabs and rashes to hives and bumps
  • Once the allergic reaction begins, the skin will develop a rash with some patches of oozing pus.
  • Symptoms will generally improve within days but some can last for months or years depending on the severity of the allergy.
  • An observation of scratching by a pet owner is the starting point for many visits to the veterinarian.
  • Scratching is the most prevalent symptom that drives dogs to veterinary clinics4—and with good reason. Scratching is caused by a combination of skin allergies and skin diseases.


Licking, biting, and clawing till the skin is clearly broken in a dog indicates an underlying condition that will necessitate veterinary intervention to resolve.

The following are five of the most common reasons of itching in dogs, which can cause them to scratch and scratch and scratch and scratch and scratch and scratch and scratch and scratch.

1. Dermatitis due to a flea allergy

Flea allergies are frequently the first thing that comes to mind when we observe a dog scratching, even if the scratching is unrelated to anything. In spite of the fact that your home may be free of fleas, your dog may still pick up fleas from the environment.

Whatever the cause, your dog may become depressed and irritable due to itching, hair loss, and scabs brought on by flea infestation.

Repeated exposure can result in abnormal, exaggerated reactions to even a single flea bite, making it even more difficult for a veterinarian to determine the source of the problem.

Infections and inflammation are frequently caused by these hypersensitivities.

Treatments and preventives will be discussed with you by your veterinarian, with a focus on prevention.

2. Atopic dermatitis is a type of dermatitis that affects the skin.

When the genetics and environment of each individual dog collide, atopic dermatitis develops in the dog. It is one of the most frequent types of allergic dermatitis in dogs, accounting for around 5% of all cases.

For the most part, atopy is defined as an itchy, steroid-responsive condition that is not triggered by anything with legs, anything that can be manufactured in a laboratory, or anything that dogs consume.

However, rather than being caused by allergens in and of themselves, Atopic dermatitis is caused by an incorrect immune response. Although molds, dust, and pollen can cause the illness, it is actually caused by an inappropriate immunological response.

Dogs suffering from atopic dermatitis will lick and gnaw at their paws on a regular basis, as well as scratch their faces, eyelids, and ears.

Treatment options vary, but the most of them entail avoiding the allergens, treating the condition with drugs that have less adverse effects than steroids, or desensitizing your dog by injecting small amounts of allergens into his system to change his immune system responses to them.

3. Allergies to certain foods

As with humans, canines can develop food allergies; however, their reactions may be different, such as chewing, scratching, or rubbing, which can result in secondary illnesses caused by bacteria, yeast, or fungus (see below). Hair loss, vomiting, and diarrhea are all possible side effects of food allergies.

Following a stringent temporary diet to isolate which foods your dog is allergic to, your veterinarian may propose a long-term diet to avoid the allergenic element.

Initial testing may take many weeks and will demand your meticulous attention to detail, but it is just as important as any prescription you are provided.

4. Yeast skin infection is another type of yeast skin infection.

Yeast are a common dweller of the skin and ears, albeit they are only found in small numbers.

However, they can sometimes overgrow and get infected, leading in itching, red or flaky skin, or a pungent odor, among other symptoms.

It appears that increasing warmth and humidity of the skin increases the likelihood of a yeast infection in your dog, particularly under the skin folds and in the ear canals of your dog.

The treatment of yeast skin infections can be accomplished by the use of medicated shampoos or oral drugs.

5. Bacterial infection

bacterial skin infections can occur as a result of an allergic reaction to one of the items on this list, or they can be the major cause of the itching.

Bacterial strains that are commonly encountered include Staphylococcus pseudintermedius, Staphylococcus canis, and several more.

Moisture-soaked, sticky, inflammatory skin lesions and hair loss are also common symptoms.

Any injury or damage to intact skin will result in a reduction in the skin’s ability to defend itself.

Cuts or inflammation cause naturally occurring surface bacteria to go out of balance, or they can penetrate the skin and cause infection.

This results in further gnawing and scratching, which causes more kinks in the skin’s armor and allows more bacteria to pass through the skin, perpetuating the vicious cycle even further.

The therapy for bacterial skin infections may begin with the removal of hair from the diseased regions to help the skin to dry out more quickly.

Topical therapy, including as cleaning, antiparasitic, and medicated shampoos, may also be beneficial in some cases. Veterinary antibiotics are particularly successful in the treatment of bacterial infections when they are provided in strict accordance with the veterinarian’s prescription.

Taken together with your pet, taking tablets multiple times a day may be too stressful for both of you. Instead, oral antibiotics provided once a day or an injection that lasts up to two weeks may be more beneficial in terms of treatment success.

Early detection of the source of your dog’s itching, as well as effective treatment and prevention, can improve not just the comfort of your pet, but also the overall quality of life for your entire family.
