Should you pull it off a tick from your dog's belly?

You don't want to pull the tick out because its head will break off and remain imbedded in your pet. The imbedded head is liable to create an infection. Pour a drop of olive oil, or other oil on the tick's body. As the tick suffocates, it will pull its head out before dying. I have heard that a drop of dish detergent also works, but I have never tried it.
