Common Dog Skin Problems


Common Dog Skin Problems & Treatment ( how to help your pooch) are usually hard to determine because there are so many different skin problems that occur for various reasons.

Here are some Common Dog Skin Problems:

1. Dermatitis

  • Environmental dermatitis: Due to Environmental changes
  • Nutritional dermatitis: Due to nutritional Imbalance

Both these conditions lead to dermatitis, i.e., inflammation of the skin. So, in that case, you must concern your veterinarian because that is an emergency condition.

2. Fleas, Mites, Mange, and Other Critters

Fleas are parasites/small insects that feed by sucking blood from your canine companion. During feeding, they inject a minute quantity of saliva into the skin, and many dogs become allergic (usually skin allergies), which leads to intense irritation.


The dog’s response to this severe itching is to lick, chew, or scratch. This causes alopecia (hair loss) and can lead to open scabs or sores on the skin, which may, later on, become infected with harmful bacteria.

The area most usually involved is over the rump (just in front of the tail), although all body areas can be affected. In long-standing cases, the skin can become thickened and dark in color. Large infestations of fleas may lead to anemia, and fleas are also responsible for transmitting tapeworms to your dog.


Special shampoos or sprays are available to kill these fleas, ticks, mites etc. Also, regular grooming and combing may help give you a clue that your pet is infected or not.

3. Canine Atopic Dermatitis

It is a pruritic (itchy) skin disease of cats and dogs. In this disease, an allergic reaction occurs when an animal inhales airborne substances such as house dust or pollen or ingests a substance to which they are sensitive. The allergic reaction causes the animal to lick, bite, rub, or scratch. Unlike man, dogs with atopic dermatitis only occasionally sneeze, cough, or get asthma. Instead, they itch severely.

Signs and Symptoms

The itching may be limited to certain areas or maybe over their entire body. Usually, the armpits, face, ears, feet, and front legs are affected. This contrasts with a flea allergy where the groin, tail, rump, and thighs are typically affected. About half of the dogs with atopic dermatitis will also be allergic to fleas, ticks, and manges.


Atopic dermatitis can be cured with proper care and management. Usually, steroids (cortisone-type drugs) are used for the treatment of atopic dermatitis. They are other beneficial anti-itch and anti-inflammatory medications you can also use with a prescription from your veterinarian.

4. Food & Drug Dog Allergies

The most common food allergens in dogs consist mainly of proteins, especially dairy products, beef, chicken, lamb, soy, chicken eggs, or gluten (from wheat). Each time a dog eats food containing these substances, the antigen-antibody reaction occurs, and your dog’s skin may become itchy or full of rash.


Once the haphazard food substance has been identified, a diet chooses afterward does not contain these particular substances. Today, many tasty, hypoallergenic diets can be fed to your dog for the rest of your pet’s life.
Similarly, expire drugs or drug overdose also lead to skin allergies sometimes.

Use a home-cooked diet in the case of food-allergic dogs is the best solution

What is an allergy?

Allergies are the immune system’s response to external stimuli. When an external substance enters the body, the immune system interacts with the foreign material and reacts appropriately to keep the body healthy. Allergies are usually the result of an overreaction by the immune system, which manifests itself in some form of physical irritation.

Although allergies are sudden, they result from prolonged exposure to a particular stimulus, also called an allergen. Prolonged exposure to a specific allergen can cause stress the immune system, and it can begin to flag the allergen as a threat. The immune system then triggers a reaction in the form of an allergic reaction, as it tries to eliminate the allergen from the body of the affected dog.

Can dogs can develop allergies over time?

As explained in the description of what an allergy is, it is relatively common for a dog to become allergic to something as it gets older. As the same stimulus frequently bombards your dog’s immune system, it begins to produce antibodies to protect itself from a long-term illness. These antibodies build up over time and develop allergies as your dog ages.

Generally, allergies to external stimuli will begin to appear after your dog reaches puberty, but they may start to appear in your dog by the age of six months. In some rare cases, allergies can take a long time to develop, and it is not unusual for dogs to develop allergies late into adulthood.

  • Inhaled 
  • Ingested 
  • Implanted 
  • Contact 

Can skin allergies be inherited from parental dogs?

Unfortunately for dogs, allergies can be transferred via the genetic material from parents to offspring. Hereditary allergies are more common in purebred dogs than in mixed breeds, but all dogs may be at risk of inherited allergies from their parents.


Genetic traits such as allergies are often passed on to purebreds because there are not many genetic mutations from one generation to the next to eliminate the allergic risk. Hereditary allergies belong to the category of respiratory, and they are usually seasonal.

Is heat rash an allergy?

Heat rash is a type of allergic reaction. Although it is not classified as one of the above, heat is an external stimulus that triggers your dog’s immune response. As a result, heatstroke can be classified as a type of allergic dermatitis.

New environments bring new allergic potential

If you have recently moved to a new area, whether across the country or in a neighboring state, there are likely to be many new allergens to deal with. Each microclimate you encounter with your dog offers a unique potential host of allergens that your dog must adapt to.

Maybe it’s a new pollen strain that doesn’t belong in your last home or a new strain of grass that your dog isn’t used to. You may have moved somewhere that is five degrees hotter on average, and you need tips to take care of your dog in warm weather.

Although five degrees may not make a big difference to you, an increase in temperature can be a tipping point, which can cause your dog to become allergic to too much heat.

Note: New environments contain new allergens that your dog may become sensitive to, and you must monitor your dog if and when you change its environment
