To be able to treat a certain skin change, the crucial step is to determine the exact cause of your dog’s condition.

So, a good way to start is by reading our following list. This list provides you with the common causes of crusty scabs on a dog’s back.

1. Wrong Nutrition

Nutrition is a vital segment of a dog’s overall health. A healthy and high-quality diet will also be visible on your dog’s fur, which will be healthy and shiny.

On the other hand, if the food you are feeding your dog is not the best choice for your pooch, you may notice this on your dog’s skin. Your dog’s fur and skin may become stiff and cracked and may begin to look lifeless.

Therefore, crusted scabs on the dog’s back could indicate that your dog’s diet lacks protein and nutrients. If you are unsure why your dog does not like the dog food you are feeding it, it would be best to consult a veterinarian.

He might recommend changing your dog’s diet entirely or adding some supplements to your dog’s nutrition.

2. Allergies

Allergies can be the reason for the appearance of scabs on your dog’s back.

Dog allergies can be divided into skin allergies, food allergies and environmental allergies. Skin allergies, also called Allergic Dermatitis, are the most common, and fleas most often cause skin allergies in dogs.

Allergic reactions to food in dogs can be recognized by symptoms such as scabs on a dog’s body, itching, and gastrointestinal problems, such as diarrhea and vomiting.

Environmental allergies can also cause atopic dermatitis or crusty scabs in dogs. These allergies occur when a dog inhales allergens inside the house or outside. Environmental allergens include dust, dust mites, pollen, etc.

There are some common symptoms that you will notice in your dog, no matter what type of allergies he is dealing with. Those are crusted scabs, itching, frequent sneezing, and swelling of the dog’s face and lips, and the dog may constantly lick.

3. Improper Hygiene

Bathing is essential in the hygiene of every dog, so probably every dog ​​owner has once asked themselves: How often should I bathe my dog?

There is no universal answer to this question. This will significantly depend on the dog breed, as well as what your dog’s lifestyle is like. Some dogs will need bathing every three to four weeks, while for some others, a bath two or three times a year will suffice.

But, it is not only vital that you know how often you need to bathe your dog; it is also essential that you also know how to clean your dog.

Improper hygiene can cause the appearance of crusty scabs on your dog’s back.

The shampoo you use on your dog should be dog shampoo, not human, and the pH balance is different for dogs and humans. Therefore, products that humans use should not be used on dogs.

If you are unsure which shampoo would suit your dog best, find good options on our list of shampoos for all types of dog fur, which also smell great!

Here we will point out that many dog ​​owners make one mistake when bathing their pets; bathing them too often. If you bathe your dog too often, you may be removing the natural protective layer on its skin, which then results in scabies.

4. Bacterial Infection

One of the possible causes of crusty scabs on a dog’s back is a bacterial infection. The most common bacterial infection is Folliculitis.

You will notice pus blisters if the dog suffers from this bacterial infection, and these blisters soon burst and turn into crusted scabs. There are various causes of this bacterial infection, the most common of which are flea allergy or food allergy.

5. Fungal Infection

Peeling scabs could indicate a fungal infection or ringworm in the dog.

Fungal infection can occur as a result of contact with another infected animal, but also due to too frequent bathing of the dog, as well as exposure of the dog to a humid environment for a long time.

A fungal infection can be identified by the dog scratching constantly and shedding hair from areas of the body that are affected by the fungus. In addition, inflammation, redness, and scabs will occur.

6. Yeast infection

Yeast infections in dogs develop due to an unbalanced immune system and are encouraged by medications and hot weather. This kind of infection can be noticed by the dog’s red and irritated skin, and the dog will also constantly scratch and lick itself.

In some cases of yeast infection, veterinarians advise changing the diet, and in others, the use of oral medications.

It is also recommended to treat the dog’s skin with anti-fungal shampoos or a cream containing benzoyl peroxide.

7. Hormonal Problems

Hormonal imbalance in dogs can cause skin changes. So, if you have noticed scabs on your dog’s back, this may be a problem that comes from within and is a hormonal disorder.

Such skin problems in a dog can be associated with hormonal diseases, such as hypothyroidism or Cushing’s disease.

Additional symptoms you may notice are hair loss, and the dog might drink more water and pee more frequently.

Also, you may notice that the dog’s skin has acquired a different pigment.

8. External Parasites

Most dogs will struggle with external parasites at least once in their lives. Not every parasite is equally dangerous for a dog, but one thing is sure – every parasite is irritating and makes our dogs feel uncomfortable.

The most common external parasites are fleas. Typical symptoms of this external parasite are itching and hair loss in the dog. Additionally, the dog is likely to constantly lick and scratch, causing crusty scabs and hot spots on its body.

Also, affected areas can become infected with bacteria, too, which can cause secondary infections.

If you notice flea bites in your dog, you should contact your vet right away. A flea infestation might lead to more severe health issues, like blood loss.

Besides fleas, mites are an additional common external parasite that attacks dogs.

Demodex mites cause demodectic mange in dogs, while mange mites cause sarcoptic mange. Demodectic mange is not contagious and cannot be transmitted to humans, while sarcoptic mange can.

9. Autoimmune Disease

Autoimmune diseases are incurable diseases of the dog’s immune system. Autoimmune means that the dog’s immune system attacks its cells. Such immune disorders are manifested in the form of acute skin ulcers.

Dogs’ most common immune disorders are hypothyroidism, lupus, and anemia. Autoimmune diseases can be pretty difficult to recognize but also to treat.

Some dogs are genetically more prone to developing such diseases; in some, the disease can occur due to consuming some medicine.

Of course, the earlier the disease is detected, the better it is for diagnosis and treatment. Therefore, every dog owner should thoroughly check their dog’s hair and skin regularly.

10. Skin Tumor

Unfortunately, crusted scabs can sometimes indicate a skin tumor in a dog.

Along with these skin changes, you can also notice changes in the dog’s behavior, so the dog might look tired all the time.

This is a severe skin condition that needs to be treated with surgery, radiation, or chemotherapy.
