There is a cool little tool - a tiny 'spoon' with a slit in it that allows you to remove the tick, head & all, without touching it. Pet-Medic Tick Removing Kits

I have used it: get one, keep it handy, Use it! then get your pets on a good tick /flea preventative, like Frontline, and keep 'em on it!
Ticks can carry Lyme Disease as well as other diseases that can be passed on to YOU as well as your pets. If at all possible, you want to remove the tick before 24 - 48 hrs have passed, before it swells enough for body fluids to exchange much. For that reason, you do not want to handle the tick, tear it apart, or squish it. the blood it has sucked up can pass disease even if the tick is removed.
Once you remove it - to make sure it is dead, put it in a plastifc baggie with some rubbing Alchohol - to kill any germs or disease - and show the baggie to your vet. (drowning completely in alchohol WILL kill and disinfect the bug, but you can't 'drown' it while still attached!) The Vet can tell you if the tick is a type that can carry Lyme disease. Make sure you wash your hands thoughroughly after removing the tick, wash the dog's head, & anything you used, as well. Even if you get all the tick, before 24 hrs, & it isn't a 'Lyme" tick, your dog can still have an irritated itch or allergic reaction to the bite. clean well!
The Alchohol, vaseline, hot match/ needle, etc are all "old" remedies that are outdated because they never worked very well, and before people really knew about Lyme disease, etc. (If someone put a hot match to your butt, would you let go? or dig in deeper to get away from it? and what about the poor dog? he gets the hot match, too?)
