Dogs have been around since the evolution of wolves in the animal kingdom. Dogs were kept as pets in Europe 20,000 to 40,000 years ago. More than 78 million households and people in the United States have a dog as their preferred pet. These cute, pesky pups are fast, relentless and playful. With that, playfulness also comes to the risks of getting skin allergy from the environment around them. In this article, we discuss dog skin allergy causes, treatment, and home remedies.

Dog Skin Allergy: Causes and Remedies

Skin allergies in animals aren’t uncommon. The polluted air around us has many airborne allergens. This can make all kinds of skins, irritated and itchy. Dogs are no exception.

Skin allergies in dogs are also known as atopic dermatitis. This is an inflammatory, recurring disease caused by dust particles and pollen in the air. This is extremely difficult to avoid dogs because most dogs are inevitably coming in contact with the outside world.


Sensitivity issues are normal for dogs. Food allergies, sensitivity to environmental elements, fleas, and other bugs are significant causes. 

Signs that your pooch has hypersensitivities incorporate:

  • Tingling, 
  • Face scouring, and 
  • Paw licking. 

After some time, crusting, scabbing, wounds, and bleeding may happen. Yeast or bacterial contaminations are likewise normal in hypersensitive pooches. Numerous dogs with incessant ear contaminations also experience the ill effects of hidden allergies.

Some of the many types of skin allergies are mentioned below:

Atopic Dermatitis

The table below presents some causes and reactants of Atopic Dermatitis

Causes of Atopic Dermatitis

Food allergies Beef, dairy, and wheat
Sensitivity to environmental elements Pollens of grasses, trees, and weeds, Dust mites, and molds, depending on the timing of the allergy.
Flea Allergies Flea bites. Proteins in flea saliva can cause an allergic reaction that can stay up to 7 days!
Bacterial hypersensitivity Staphylococcus Hypersensitivity Can occur when the skin is in contact with Staphylococcus (Staph) bacteria

Food allergies

Food items of all ranges, qualities and price points can cause allergies. Usually, in the human body, the signs of allergic reactions are visible in their skin. But allergy in dogs sometimes affects their immune and gastrointestinal system too. Symptoms can build over long periods of time. So it is unsure what in their diet might’ve caused this.

Sensitivity to environmental elements or inhalant/ contact sensitivities

Careful assessment of your pooch’s hair, including insect brushing, will often show bug bite sensitivities. Regular tingling, particularly if the zones included are your canine’s feet, face, and ears, most of the time indicate inhalant/contact sensitivities. 

Flea Allergies

Fleas are regularly the reason when the itching is focused on the lower half of your pooch’s body, including close to the tail, lower legs, and crotch. The deadly proteins in their saliva can cause an extreme reaction.

Bacterial Hypersensitivity

Staphylococcus Hypersensitivity occurs when the skin comes in touch with Staphylococcus (Staph) bacteria. This causes an immune system overreaction. This is more likely to happen when flea allergy and/or inhalant allergy and hypothyroidism are concurrently present in your pup.

Yeast Infection

Uncontrollable scratching their ears, licking and chewing their toes points towards a yeast infection. 

Symptoms include discolored skin patches, itchiness usually in the paws or ears, where the yeast had a nice, warm, bacteria-infested area to procreate.


A bacterial infection that forms scabs, red bumps, and scarring on the skin. This usually occurs with other skin issues such as injuries, allergies, and mange.


It’s when the skin becomes greasy and creates scale-like flakes. In some cases, if this is genetic, it can last forever.


These fungi form ‘ring-like’ patches on random areas on their body and are often seen in the head, ears and around limb area. 

Less than a year old puppies are most vulnerable to this infection. Various anti-fungal treatments are available.


Extreme shedding caused by stress, malnutrition. Medication varies on the type, breed and what illness they already have.

Mange (Mites)

Disease caused by mites. Sarcoptic mange, aka canine scabies, transmits easing amongst dogs. This results in extreme itchiness, reddening, and loss of hair.

Dog Skin Allergy Diagnosis

Your pooch’s medical history and a physical assessment will provide ample information about their specific allergy. 

  • It is often assumed that bugs are the reason when the tingling is focused on the dog’s lower half, including areas close to the tail, lower legs, and crotch. However, a careful examination of the body hair, including insect brushing, will help diagnose them with flea or other insect bite sensitivities. 
  • Signs of inhalant/contact sensitivities include seasonal itching, especially if the itchy areas are your canine’s feet, face, and ears.
  • There is a chance that the itchy sensation is available all year, and is less receptive to cortisone or antihistamines. Food allergies are considered a possibility at that point. 
  • Blood and additionally, skins testing are necessary to draw to such conclusions. To identify the offending antigen, tests including intradermal skin testing can also be performed.
