Okay, I'm a summer camp-survivor. I've had...let me see...at least 4 ticks as a camp counselor, and 1 when I was little. All deer ticks, the little black ones. I never got Lyme's disease, thankfully, but three other counselors all had to go on antibiotics one summer because they got Bull's Eye rashes. (That doesn't mean you WILL get Lyme's disease, it just means you might.) They also trained us in first aid courses on what to do.
--If you find a tick, take it off with tweezers in a brightly lit area. Pull it straight out so that the mouth doesn't break off and stay in the bite--the saliva can continue to infect you after the tick is dead. Try and put the tick in a jar and bring it to a doctor for testing.
--It takes 24 hours to infect you, so if you're in an area where you might get ticks (grassy areas are especially dangerous), check after you get home. Have someone help you look. They like warm, dark places, like armpits, elbows, groin, etc.
--They climb around for a while before they bite you. SHOWER or jump in a pool/lake. This will wash the ticks off of you. If they have already bitten you, they will let go when submerged--they can't breathe and suck if they're in water.
--Watch the bite area for the "Bull's Eye rash." This will be a big red area that looks like a red bruise that surrounds the bite area. This is a sign that you might have Lyme's disease and should seek medical attention.
But all this only relates to deer ticks. I know nothing about dog ticks; our dog never got them, and I've never gotten them either.
If your tick looks anything like, this, however, you have another problem entirely:
