Any kind of crusts on the dog’s body indicate a problem, most often of a skin nature. Many masters begin to worry only when the process spreads or when alarming symptoms appear (severe itching, oozing, large bald patches, pet’s restless behavior, etc.). But, it will not be possible to determine the nature of the origin of the crusts on the dog’s skin only by visual inspection.

Complex diagnostic measures will be required to exclude demodicosis, dermatitis, lichen, parasites and other possible causes.

The List of Possible Illnesses

Scabs on the skin of dog should not be considered an independent symptom, since in rare cases they appear without itching, peeling, redness or hair loss. Therefore, first of all, the likelihood of the presence of the following diseases is considered.

Allergy

It is necessary to exclude first of all, since in such breeds as pug, Shar Pei, York, bulldogs, boxers, almost all skin problems are associated precisely with manifestations of various kinds of dermatitis. Redness, peeling and crusting appear in different parts of the body.

When scratching, weeping wounds form in these places. Hair loss is clearly visible in animals with a large undercoat, less noticeable in smooth-haired breeds. In severe cases, complete baldness can be observed.

Food can provoke all of the above (in more than half of the cases). For some breeds, one ice cream or a piece of chocolate will be enough for the allergic reaction to manifest itself in all its glory. Cases of contact of an animal with plants are considered the second most frequent.

For some breeds, contact with many plants can result in severe burns. Bloom usually reacts with watery eyes and sneezes. Eyes may swell. The most dangerous allergens for dogs are chemicals that can be found in detergents. Access to them should be limited.

Masters of pets with severe dermatitis need to understand that it will not be cured once and for all. But, you can try to control the manifestation, which are painful for the four-legged. A special diet, hypoallergenic feed is selected, contact with dangerous plants or potential allergens is excluded.

Demodecosis

The second most common cause of skin crusts in dogs of all breeds. It is more often found in puppies (called the juvenile form) and in older individuals.

This is due to the fact that demodicosis cannot manifest itself. Something must provoke it.

In old pets, this can be internal diseases (liver, almost, heart), a tumor process (very often combined with the activity of a demodex mite) or prolonged use of antibiotics, which provoked a sharp decrease in immunity.

In puppies, small lesions can heal on their own without the use of any therapeutic measures. In dogs after 7 years, it is imperative to look for the root cause, since without its exception, the fight against demodicosis will be useless and ultimately can lead to complete baldness of the pet.

Pyoderma

A common phenomenon that can occur as a complication of major diseases (demodicosis, allergies, lichen). With pyoderma, the skin always turns red and dry crusts appear at the site of the lesion, which constantly crumble.

In the case of deep skin lesions, pus is present under the crusts. To make a diagnosis, a cytological examination of scrapings from sites of inflammation is mandatory. The success of treatment will depend on the identification and control of the underlying cause that triggered the pyoderma.

Pyoderma itself is treated with a long course (5-7 weeks) of antibiotics.

Fleas

Flea bites very often lead to the formation of hard crusts on the skin of dogs. Common localization are back, ears, tail. The difference from allergies and demodicosis is that hair almost never falls out. Crusts can only be found under the coat. They look like dandruff or peeling that remains on the hands after stroking the animal.

It is recommended to treat all animals living in the house with drops. With frequent relapses, the home must be disinfected.

Dermatophytosis

An unpleasant skin disease of a fungal nature, which manifests itself in the form of small bald patches surrounded by white crusts at the edges. In some cases, weeping or purulent rash may be present inside the lesion.

An accurate diagnosis can be made only with the help of microsporia of crops of a culture taken from bald patches. To confirm the diagnosis, a Wood lamp can be used, under which the lesions will give a bright green glow.

Treatment is long-term with possible relapses if the home and all hard surfaces where spores may persist are not disinfected.

Definitely, the appearance of crusts in a dog at any age should not be ignored by the owner, since when the process spreads throughout the body, long, painful treatment will no longer be enough.
