If there is a tick on the dog, you should first apply alcohol on the tick to make the head of the tick relax or die. After a few minutes, use pointed tweezers to remove the tick. This method requires certain skills. You can also use topical anthelmintics. Apply it on the back of the dog's neck, and the ticks will fall off automatically. After removing the ticks, the skin should be cleaned and anti-inflammatory drugs should be applied. Be careful that the ticks cannot stay in the skin, and the dog should be dewormed externally on time.
