Dog ticks are most afraid of external anthelmintics and alcohol. If there are ticks on the dog, it is best to drop alcohol on the tick. Wait for about five minutes, and the tick will be anesthetized. At this time, it will be anesthetized. Just use tweezers to slowly remove the tick. When removing, be careful not to break the tick's mouthparts to avoid skin infection of the dog. If you want to prevent the dog from being infected with ticks, you need to perform an in vitro examination on the dog once a month. Deworming can effectively prevent your dog from being infected with parasites.
