I'm an avid camper, so my dog and I have dealt with many ticks before...I've had over 20 stuck to my one ankle at one time (haha, I got lost in the woods that day... :roll: ). Never had one on the horse, though.
For getting ticks out of humans, you can use tweezers, but be really careful: if you squeeze the head too hard, it will squish toxic juices from the bug into your body and you could get really sick. There are also instruments you can buy called tick spoons. I've heard heat works too--hold a lighter up to the tick (being careful not to burn yourself, of course!) and it will up and leave, or at least loosen. Also--once you remove the tick, make sure you get the whole thing: sometimes, the head will stay stuck to the area, and oftentimes legs will also remain in the sore. That's not fun.
