Sarcoptic mange in dogs is caused by a tick. The causative agent of the pathology is an intradermal mite, which can be transmitted to a new host through direct contact with an infected animal. Females make passages under the skin in 1 day, in which they lay offspring. The disease affects the skin and is accompanied by severe itching. It is worth considering that this pathology can develop in any season of the year. This disease is contagious, in humans it can cause the development of an allergic reaction, called cc.

    4.1 Injections


Typically, parasites attack the dog in areas where there is no thick hair on its body, most often they can be found on the ears, hock and elbow joints. Symptoms become apparent 14 days after infection. It is worth considering that the mites easily move to other areas of the host's body, due to the constant itching, the coat gradually becomes sparse, sometimes such a loss of hairline reaches alopecia. The animal combs the affected skin until papules, erythema, scabs, excoriation appear, and in some cases superficial bleeding opens.

If the animal is not provided with timely medical assistance, the pathology develops into a chronic form, which is complicated by:

  • lichenification;
  • hyperpigmentation of the skin;
  • the appearance of density on the surface of the lymph nodes.


The main symptoms appear 7 days after the infection of the dog. In the early stages, the disease usually makes itself felt very sluggishly. You can suspect parasites in your pet if the following symptoms appear:

  • the development of nodules in the area of ​​the nasal backs, ears, as well as nodular formations can form on the brow ridges;
  • the appearance of nodules completely filled with a whitish or clear liquid;
  • the presence of severe itching;
  • if the bubbles are damaged, scratches and scabs develop;
  • the hairline looks untidy due to the sticking of hairs under the influence of the liquid that the epidermis secretes;
  • if the disease manifests itself in an atypical manner, a large amount of dandruff appears on the pet's coat.

Diagnostic methods

To diagnose a parasitic lesion, the dog needs to be shown to an experienced veterinarian who will prescribe the necessary tests carried out in a laboratory. In no case should an animal be treated on its own or on the basis of data obtained by correspondence.


However, the fence should only be carried out in an area of ​​the body that the pet cannot reach to lick it. When carrying out diagnostic measures, you need to know that in half of the cases, such studies give an unreliable result. Because of this, doctors usually prescribe treatment for sarcoptic mange when the characteristic symptoms begin to manifest actively.

If after the treatment there is an improvement in the animal's condition, the disease is diagnosed in an anamnestic way. Some pet owners confuse sarcoptic mange with atopy, which is an acute reaction of the epidermis to an unsuitable animal feed. Also, this pathology is sometimes confused:

  • with folliculitis;
  • with dermatitis;
  • with generalized pyoderma.

Sarcoptic mange differs from all these diseases in that itching sensations do not decrease even after taking steroid medications.

How to treat

First of all, a sick animal must be completely protected from others. It is worth considering that a person from an allergy that has appeared should be treated only with its acute course, in other cases, allergic symptoms go away on their own a month after the pet recovers.

Next, the dog's coat is treated with a special anti-seborrheic shampoo. Those areas of the epidermis that are damaged by papules are cut short or shaved. Then all scabs and dried exudate are removed from the epidermis.

After that, the dog is washed with an acaricidal medication at intervals of 14 days. A positive therapeutic result can be obtained using a 0.5% emulsion of Shchudrin, Karbofos, Dikresil, a 0.155% emulsion based on Diazinon water, a Hexachloran emulsion, which contains a gamma isomer in a volume of 0.04–0.05%.

If sarcoptic mange is characterized by focal spread, it is treated twice or three times with an oil solution of ASD-3, the treatment interval is 3–7 days. During treatment, it is imperative to use a muzzle so that the dog cannot lick the treated areas of the epidermis. Otherwise, licking the drug can lead to poisoning of the pet, and in some cases, his death.



Also, sarcoptic mange in dogs is treated with subcutaneous injections using Ivermectin. Injections are given 2-3 times with an interval of 7-14 days. However, this medication cannot be used to treat collies. For Shelties, Terriers, Bobtails, Briards, as well as dolichocephalic breeds, this medication is used with great care.

To relieve itching, the animal is injected with Prednisolone at a dosage of 1 milligram per 1 kilogram of body weight. The course of treatment is 3-5 days. Only one dose per day is allowed.

When sarcoptic mange appears, one should not only carry out active therapeutic actions, but also carefully monitor the environment where the pet lives. In winter, all dog things are treated with antiparasitic drugs, boiled, sprayed with 2% chlorophos. In the summer, all things just need to be laid out in the sun. Ticks will completely leave them after 18 days.
