Causes Of Dog Licking Paws And Scratching Ears

Dogs lick their paws and scratch their ears incessantly.

It’s very discomforting and is potentially harmful to the dogs if uncontrolled.

An initial sign of this disorder is the appearance of reddish patches on the skin (possibly from the friction of scratching and licking) or skin eczema on the head, chest, hips, or any other part of the dog’s body.

These skin changes usually become sore and irritating.


Dogs with compulsive scratching, licking, and chewing behaviors have a variety of causes. They can also be dangerous.

A few causes have been attributed to this behavior, among which are the following:


Seasonal allergies are implicated in the itchy skin behavior of dogs.

They affect the dog’s paws, face, ears, and to a lesser extent, any other part of the skin.

These allergies, especially during late summer, arise from different allergens the dogs could be exposed to, like foods, mold, dust, pollen, pesticides, grass, etc.

Contact with any of these allergens would elicit an allergic reaction by inducing the mast cells of the dogs to release histamine.

It is histamine release that is responsible for all the allergic behavior of dogs.

Atopic skin allergies

Atopic dermatitis is one of the most frequent types of allergic dermatitis in dogs, and it is caused by an interaction between a dog’s genetics and its environment.

It results in itches and licking, although the cause is not linked to contacts and exposures.

Although exposure to allergens elicits atopic dermatitis, its actual cause is an immune response arising from a genetic predisposition.

Atopic dermatitis causes dogs to lick and chew their paws and regularly scratch their face, eyelids, and ears.


Dogs poop in large sizes. When the housing is not cleaned often, and the poop is left to decay in the cage, it could attract pests.

Additionally, the cage would become infected from the decaying poops.

It forms an origin for a secondary cause of licking paws and scratching ears in dogs – pests and infections.


Consider the chances that licking paws and scratching the ears incessantly in dogs could be emanating from a place of pain.

The dog may be responding to a specific or nonspecific pain within the body or on the skin.

It may be due to physical injury on the skin, paw joint dislocation, arthritis, or any other injury.

Presence Of Pests

The common pests that leech on dogs include fleas, ticks, and mites.

These parasites can attack dogs for a long time without being noticed because they are not naked to the eye except for ticks.

Fleas are frequently the first thing that comes to mind when we witness a dog scratching for no apparent reason.

Even in flea-free homes, your dog can still collect fleas from the outside environment.

Scratching and licking associated with flea infestation are grave and can drive your dog insane, regardless of the source.

Repeated exposure can induce abnormal, exaggerated symptoms to even a single flea bite, making it even more challenging to determine the source.

Hypersensitivities frequently cause infections and inflammation.

Your vet will go over treatments and preventative measures with you, focusing on prevention.

It becomes crucial to check on your pet dogs for any sign of parasitism.

Anxiety And General Fatigue

Dogs may lick their paws and scratch their ears out of boredom when they may have obsessive-compulsive disorder.

It usually happens when the dog is lonely, tired, or anxious.

The dog feels better once you removed the source of boredom or handled it right, such as a change of environment.

Scaly Skin

As seen in the winter season, weather changes can lead to a dried skin condition in dogs.

Another culprit is the depletion of adipose tissue in dogs.

Any condition that will cause the dog to lose moisture can lead to dry skin and, consequently, to licking paws and scratching their ears.

Hormonal Changes

Steroids are one of the hormones that maintain the skin moisture of dogs.

Abnormally low steroid hormones in dogs could predispose their skin to infections.

The presence of skin infections can cause itching and lick in dogs.


Bacterial infections

A dog could develop a secondary bacterial infection from licking its paws and scratching its ears over an extended period.

With incessant touch, the organic skin barrier ruptures.

This broken barrier will expose the skin to opportunism by the normal bacterial microflora of the dog’s skin.

This infection increases skin irritation, leading to aggravated scratching and licking.

Fungal Infection On The Skin

Another cause of licking paws and scratching ears in dogs is a yeast infection on the skin of the ears and paws.

Yeast is a typical flora of the skin and ears, but only in small amounts.

However, they often overgrow and get opportunistic in the presence of triggers like depleted immunity.

Like an infection, they infect the skin, causing itching, red or flaky patches, and a strong odor.

Dog’s skin folds, in-between paws, and ear canal are damp; therefore, there is an increased risk of yeast infection in these parts.

You can use medicated shampoos or oral drugs to treat yeast skin infections.

Ear Infection

Histamine production can damage the delicate skin lining the dog’s ear during inflammation.

Dogs with seasonal allergies are more prone to ear infections.

If the interior skin of the ear becomes irritated and inflamed, the ear bacteria (microflora) cause an infection.

The ear’s dark, warm, and damp environment enables bacteria to thrive and increase.

If your dog frequently scratches his ear, you must take him to your veterinarian for ear cytology.

We call this ear cytology when we take a cotton swab from the inner ear, stain it, and examine it under a microscope to see if the cause of the infection is bacteria or yeast.

Handling Dog’s Allergies

A “hot spot” is a red, wet, inflamed area that develops as a result of persistent chewing, licking, scratching, or rubbing.

It could be one of the first indications that your dog has a problem.

While hot spots, also known as “acute moist dermatitis,” can appear anywhere on your dog’s body, they are most frequently found on the head, chest, or hips.

Hot spots can quickly grow large and extremely sore because dogs frequently repeatedly scratch, lick, or bite at an area once it becomes irritated.

As soon as you notice a problem, consult your veterinarian because there are so many reasons why dogs chew or scratch.

In order to develop the most effective treatment strategy, the veterinarian will assist in identifying the behavior’s underlying cause.

Depending on what led to your dog’s compulsive behavior, this could involve:

  • Lifestyle changes for the dogs. Monitor their food for possible allergic reactions. You may do this by introducing one type of feed per time while gradually looking out for any signs of allergies.
  • Identify and Eliminate known allergens. When you successfully identify an allergen, substitute for or withdraw the cause. There is also another approach which is called desensitization. You expose the dog to the allergen to induce immune reactions and gradually withdraw the allergen.
  • Change their housing to eliminate pests and parasites. Use compatible pesticides.
  • Address anxiety or boredom through a change of environment and freedom.
  • Consult a veterinarian for counseling on their skin protection and treatment of the scratching and licking behavior. The vet may recommend over-the-counter medications, or additional anti-inflammatory drugs, such as steroids, to get them through the worst of the allergy season.


Dogs lick their paws and scratch their ears due to anomalies. These are not healthy habits of dogs.

The common causes are allergies and infections from environmental exposure and genetic predisposition.

Knowing the particular origin of the paw scratching and ear licking is necessary for selecting the best treatment.

While over-the-counter medications are an option, seeking the advice of a medical professional is really advisable.

It is essential to check with the veterinarian whenever a dog begins to exhibit these behaviors.

Moreover, identifying the cause of the licking and scratching is paramount for preventing and removing the source of much discomfort to the dog.
