Sarcoptosis or itchy scabies in dogs is a parasitic infestation caused by small ticks of the genus Sarcoptes canis. The disease itself is not too dangerous and can be easily treated if it is timely. But in the case when the initial stage is missed, sarcoptosis can lead to serious consequences, up to the death of the pet from secondary infections. How to treat scabies in a dog and how to detect an ailment at the very beginning of development?
Sarcoptosis affects all pets, regardless of general condition, age and breed. Most often, ticks fall on the dog’s coat during contact with an infected animal. But there is a "workaround": ticks survive in the environment for about two weeks, can be on human clothes, on the ground and grass, on a common litter or comb. Itchy dog scabies in dogs causes symptoms 2-3 weeks after the introduction of the parasite into the epidermis. The incubation period can be reduced to a few days if the pet has sensitive skin and / or if the dog has been attacked by many parasites.
Under the microscope
The smallest roundish parasites of no more than 0.5 mm in size penetrate under the skin, gnawing passages and tunnels. They feed on particles of the dermis, capable of reproduction only on the body of the "host". If a scabies mite is found in a dog, treatment should be started immediately, as these parasites multiply very quickly, "occupying" new areas of the skin. Inside the courses, the female lays up to 60 eggs for the entire life cycle, which lasts about two months!
Symptoms of scabies
Owners rarely pay attention to the first symptoms of scabies in dogs: "Just think, a little red spot. It will pass ...". But the spot gradually increases, itching, blushing and swelling. The first red dots appear in places with short hair and thin skin, where ticks are easier to penetrate. Without treatment, scabies in dogs spreads to the entire body, a red rash covers the abdomen, ears, lower back, hips, and chest.
Scabies causes a severe, unbearable itch. The pet itches constantly, damaging the skin with teeth and claws, rolls on the floor, rubs its sides against the walls. Pustules, ulcers, fistulas, drying crusts and scales form on the skin. When the scabies mite in dogs manifests symptoms in all its glory, the pet begins to bald profusely, and its skin coarsens, becoming covered with a keratinized layer of an unnaturally gray or reddish hue. Bacteria penetrate deep nonhealing combs, which significantly complicates the treatment of scabies in dogs. The pet loses its appetite, nervousness appears, sleep worsens, body temperature rises by 1-2 degrees.
Itchy ticks that provoke an ailment in dogs can only feed and breed on these animals. On human skin, they gradually die of hunger, are not able to gnaw deep tunnels and are not capable of reproduction. However, if a dog’s scabies mite is found, treatment should be carried out with gloves on. This is a preventive measure against pseudosarcoptosis, an allergic reaction to the presence of parasites: the skin turns red at the site of the bite, a swelling forms, and a rash appears around the wound. Scabies from a dog to a person is not transmitted: being on the skin of a person, ticks die themselves within 7-14 days. Treatment is not required, in addition to symptomatic (removal of itching).
But healthy pets need to be protected from a tick-infected dog. The apartment is treated with steam or an antiparasitic agent. Healthy animals are prevented, even if the owner is sure that the risk of infection is minimal.
Diagnosis and treatment
Symptoms similar to sarcoptosis are caused by a subcutaneous tick in dogs (demodicosis), various bacterial infections, and fungi. Severe itching can be a manifestation of an acute allergic reaction to food. Therefore, before buying a medicine for scabies for dogs, helpfully suggested by a consultant at a pet store, be sure to contact your veterinarian. With an ailment, especially at an early stage, you can cope on your own. However, if the assumptions turn out to be erroneous, time will be lost.
To confirm or refute the diagnosis, the doctor will take the material from the affected area of the skin. But quite often (about 40% of cases), the treatment of scabies in dogs is delayed due to false negative results of the analysis: small parasites that penetrate deep under the skin cannot be detected or they simply do not appear in the area from which the scraping was taken. It is important to insist that the doctor make several scrapings from different areas of the skin, which will almost certainly allow you to make the right diagnosis the first time.
At the initial stage of itchy scabies in dogs, treatment comes down to treating the pet with a drug that kills parasites. For example, selamectin, which is part of the stronghold drops. Processing is carried out twice (at the withers, spreading the hair), with a three-week interval. Or Lawyer, twice every 28 days. When it comes to a few specks, the effectiveness is 100%. The same means can be used as a prophylaxis of sarcoptosis: the tick that has appeared on the skin of the treated dog will not have a single chance.
If the vet answers the question: "Scabies in a dog, how to treat?" there is only one answer - ivermectin, perhaps you should contact another specialist. Ivermectin is 100% effective (for which we are loved by many doctors), but it is extremely toxic. Among the side effects are respiratory arrest, bradycardia, convulsions, loss of consciousness, etc. Dull scabies, except in very advanced cases, can be cured with milder means.
In severe cases, itching and antibiotics are prescribed to reduce the number of pathogenic bacteria. Locally: wound healing, anti-inflammatory and antibacterial ointments, emulsions. To make the drug work more efficiently, before processing, the hair is cut off around the bald patches and combs, and then the pet is bathed with Peroxderm shampoo. Plus the same "Lawyer" or "Stronghold" for the destruction of ticks (2 days after bathing).
