My friend cut the hair from around her dogs eyes once, and then she took him down by the canal, and he got a tick attached to his eye ball! It was gross!! We took him to the vets (who was very angry with my friend for cutting the hair!!) and he froze the tick off with Liquid Nitrogen! I was the only one who didn't throw up! So just be careful if you are going anywhere where there are Sheep or Cows!
