To remove ticks from dogs, you can drop alcohol on the ticks and remove them after the ticks are anesthetized. You can also use pet-specific tick repellent and drop it on the dogs. After a while, the ticks will disappear. If it dies and falls off, it is best to drop it on the back of the dog's neck to prevent the dog from licking it. If there are many ticks on your dog, it is best to go to a pet hospital to find a doctor to remove them to avoid leaving mouthparts and causing skin inflammation and infection.
