Hi, to remove excisiting ticks you can start by prepping the area with rubbing alchol which will begin to kill the parasite. Next you should take clean tweasers and remove the tick. To safely despose of it I would place it in a plactic baggies with a rubbing alcohol soaked paper towel. Definitely consult your vet as ticks carry many diseases. Also they may have an idea on how to keep your pony from getting them in the future. Good luck!
