Demodex canine is a relatively stubborn disease, even if it is cured, it must be prevented. Demodex disease in dogs mainly relies on injections and oral medicines, and the dog can be given regular medicated baths and sprays on the affected area.

One**. 1.The commonly used method of Demodex canine is oral ivermectin. Not recommended for Curleys. However, other dog breeds are suitable.

Oral ivermectin is best taken orally with food. If it is possible to determine the concentration of ivermectin at 1%, the algorithm of oral dose can be more straightforward: daily oral.

For dogs taking ivermectin for the first time, to prevent side effects, it should be gradually increased to my recommended amount over 7 days, for example: Day 1: 1 7 (approximately; Day 2:

2/7（；Day 3 to Day 7 and so on. Have the owner watch the animal react during the first week of medication at home. If there is an abnormality, the use of ivermectin is stopped.

Possible side effects: anorexia, depression, vomiting, mydriasis, tremor, ataxia, drooling, coma, seizures, and death. If a gradual dosage is chosen, most dogs are able to recover by discontinuing the drug or supporting** once side effects are detected.

After the first week of observation period, you can follow the recommended days for 3 consecutive weeks.

2.For pustules, in severe cases, the pustules can be opened, washed with 3% hydrogen peroxide solution, and then rubbed with 2% iodine tincture.

3.In cases of systemic infection, antimicrobials may be combined.
