All ticks are parasites that feed off of a host. Ticks are small and grow larger as they engorge with blood from the host. Ticks can carry disease. You must remove the whole tick; do not leave any part of the head embedded inside of the dog's body.
Pour a teaspoon of liquid soap on a wad of toilet paper or cotton ball.
Hold the toilett paper with the soap over the tick firmly for up to a minute. The tick will begin to smother and it will back out on its own.
Grab the tick with the toilet paper when it backs out and place it in a jar of rubbing alcohol to drown it.
