Try and remove it as quick as possible as causing trauma to the tick by messing with it can also cause regurgitation.
Don't use vaseline - it can, in some cases, cause the tick to regurgitate its hindgut contents back into the bloodstream and obviously if its carrying a disease....not good.
Tick removers are generally the best idea - you put it round the tick and twist, can be bought from all pet shops and vets.
Other than that, we use normal tweezers on the sheep - if you do this, be very careful you don't leave the head behind - they don't grow back, get into the bloodstream etc etc - but they can allow the skin to heal over and cause a nasty infection. If you put the tweezers as parallel as possible to the skin, and get a firm hold of the head (as close to the skin as possible) and pull firmly and slowly and the tick should release its grip
If its still quite small its probably not fed much as of yet

for more information have a wee look on here www.bada-uk.org we are a self funded charity that is all about raising awareness about ticks and the diseases they carry especially Lyme Disease. It is a horrible disease, but so easily treatable if caught early. Hope you don't mind me adding to your post?
The O'Tom tick twister is really the safest way of removing the tick, mouth parts and all. You get to learn which of the two sized tools to use. As with everything it takes practise. When you twist with it, it doesn't matter which way you go so long as you keep going that way. When twisting with tweezers the tick will most likely regurgitate, so all it's gut contents bacterias and all go into the host. After it has done that is is able to back out, which is most likely why you can remove it. I'll add a link to our website and you can see it being used on there. I have 5 working dogs, and have to say it comes in so handy and unlike tweezers you aren't pulling out any hairs. Mind you have to use it quite a bit on my son too.... Hope this is of help..
