What are some simple treatment methods for canine mange?

Canine mange is a common skin disease caused by canine mange parasites. The pathogen is the sarcoptic mite.

Symptoms: The skin changes of sarcoptic mange often begin on the bridge of the nose, cheeks, base of the ears, and between the armpits. Initially, red small nodules appear on the skin, which later become blisters. After the blisters rupture, a thick yellow oily exudate flows out, and after the exudate dries, fish-scale-like scabs form. There is severe localized itching, and affected dogs frequently scratch the affected area with their claws or rub against the ground and various objects. Because the sick dog scratches and itches all day long, it becomes restless and agitated, which affects eating and resting, causing reduced gastrointestinal digestion and absorption capacity, and because the hair falls out and the skin is exposed, the dog gradually becomes emaciated, and sometimes secondary infection can occur, severely causing death.

Prevention: In ordinary times, feeding and management should be strengthened, and the kennel should be kept clean and dry; the dog should be brushed frequently to enhance skin resistance. Newly introduced dogs should be isolated and observed, and if there is no infectious disease, they can be mixed into the group. The kennel should be disinfected frequently, generally with 10%-20% lime milk or 5% hot alkali solution or 20% plant ash water for disinfection.

Treatment: For mange, a thorough examination must be carried out, the affected area must be cleaned up (hair clipped, scabs removed, washed, and dried), medication must be repeated, and thorough disinfection must be done. Sick dogs can be treated with the following several effective and simple methods.

① Use fenvalerate solution or ointment: dilute fenvalerate with water into a 1000-fold suspension and spray or rub it onto the dog's body, or add it to Vaseline to make a 1:1000 ointment and apply it, for better efficacy. ② Use 1%-2% trichlorfon solution or ointment, spray or apply it, once every other day, for 2 consecutive times, then stop the medication for 7d, and if not cured, continue the medication. ③ Use mange-removing spirit diluted into a 1:250 solution to spray or apply to the affected area. ④ Apply waste diesel oil or machine oil to the affected area; for large-area mange, apply it in sections. ⑤ Mix 1 part sulfur and 10 parts vegetable oil, then apply to the affected area. ⑥ First apply a saturated sodium thiosulfate solution (sodium thiosulfate 60g, water 40mL), and after the medicinal liquid dries, use another brush to apply 5% hydrochloric acid, and after it dries, apply hydrochloric acid once more.
