My Bat-dog is very popular with ticks. I check her at night for ticks during trips. I found that a good tick tweezer (they stay closed until you squeeze the tweezers, then they open) is much easier to use than regular tweezers. For whatever reason, Moose-dog rarely gets ticks.
I recommend folks look at photos of what the Lyme disease "bullseye rash" looks like. Some people and animals can develop an allergic reaction to the tick's saliva that is a red ring, but it goes away soon after the tick is removed (the Lyme disease rash stays around much longer).
