Causes of scabs

Your dog may have dermatitis scabs

As well as we also have to be very attentive to the behavior that our dog may have, if we see that there are signs that indicate that it presents pain, if its character has changed or if, on the contrary, it stops eating. For this reason and in this article we bring you some of the causes of scabs, the symptoms and what the solutions may be.

Dermatitis

One of the diseases that can mainly cause scabs on our dog's skin is dermatitis. There are different types of dermatitis, but there are only two that stand out since they produce this problem in the dog's skin and these two types are the following:

Atopic dermatitis

This is a skin disease that not simply can affect humans, but can also affect the skin of animals. The causes of this disease are not yet fully understood.

Experts say it is an intermittent skin disease, which appears when certain agents are present that irritate the skin and that usually the first symptoms appear at 3 and 6 months of age.

Generally, one of the symptoms of the disease is severe itching, something that is very frequently scratched, wounds and of course the much mentioned scabs on the skin.

In this same way, we can see redness in certain areas of the dog's skin and it may also be that it suffers from fur loss. This is a disease that has no cure, but it can be controlled if the dog receives all the indicated care that will be of great help to alleviate the symptoms.

Seborrheic dermatitis

It is also known by the name of canine seborrhea, this is another disease that affects the skin and occurs very frequently in dogs, which It mainly affects those areas of the face, the legs and also the torso.

This type of disease is caused because excess bait is created by what are the sebaceous glands, so we can see that yellow or white scales appear that are attached to the hair, in small crusts on the skin due to that the animal scratches excessively and added to that we can perceive an odor on the dog's body that is not pleasant.

Scabies

La scabies It is a skin disease that is caused by mites, which seek as a place to live the dog's skin to be able to feed on the keratin and also the sebum that it has, so they reproduce very quickly and spread throughout the skin of the animal's body.

In the two types of scabies there are, the dog is intensely itchy in the early stage of the disease. As this disease progresses, we can see that the skin hardens until it cracks and the scabs stand out much more. In the same way, hair loss and bad body odor occur.

Canine leishmania

Also known as the leishmaniasis, It consists of a chronic pathology without a cure, so the treatment of the disease is only to mitigate the symptoms and provide the dog with a better quality of life. After infection there is an incubation stage that can last a minimum of 3 to a maximum of 18 months, after which the symptoms will begin to manifest themselves.

The changes in the skin will be progressive and it will become thickerIn it, scabs and wounds will appear, it will also be noted loss in the weight of the animal and localized hair loss, especially on the legs, tail and head.

The dog, despite this disease without cure, can have a good quality of life as long as the treatment indicated by the veterinarian is followed and is reinforced with healthy and adequate food for these cases.

Fungal infection

Topical yeast infection can have its origin in several causesOne of them, very frequent baths, also continued exposure to high humidity environments, contact with sick animals, hypersensitivity to allergens in the environment and immunosuppressive diseases.

The dog affected by skin fungus will present specific symptoms, such as localized hair loss, intense itching and scratching, inflammation, redness, scabs and dandruff. In the case of scabs, they usually have a rounded shape.

Canine pyoderma

It is a bacterial skin disease caused by an invasion of fleas in the dog, which is considered a simple infection or it can originate from a health disorder or other pathology and turn into a complex infection. Among the disorders that can give rise to complex infection we have: leishmaniasis, skin hypersensitivity and others.

The symptoms are swelling, redness, excessive itching, presence of scabs and wounds, the latter should be attended to so that the condition is not aggravated by infections, presence of scabs, bleeding and pus.

Poor diet or improper hygiene

The answer to the scabs on the dog's skin may be in the diet, hygiene habits and in general the care it receives. When the canine is given a balanced and quality diet, in some way, it is guaranteed a healthy life that helps to strengthen its immune system.
