If there is a tick in the dog's ear, you can drop alcohol on the tick. Wait five minutes for the tick to become paralyzed, then use tweezers to slowly remove the tick. Be careful not to break the tick when removing it. If you don’t know how to operate the insect’s mouthparts yourself, it’s best to go to a pet hospital and ask a doctor to get it.
Tips:
You should bathe your dog regularly to repel insects, and try not to take your dog to places with a lot of mosquitoes, such as grass, to avoid being infected with parasites.
