If the dog is infected with ticks, if there are relatively few, you can use alcohol drops on the ticks and wait for the ticks to be anesthetized and remove them; you can also use dog-specific external anthelmintics, which will remove the ticks in about 1 to 2 days. Kill it and wait two days before removing the tick. You can also give the dog a medicated bath directly.
Tips:
Usually pay attention to the dog's hygiene, do external deworming for the dog once a month, and do not take the dog into the grass.
