I live in Minnesota and during the summer drive my jeep alot.Every year I bet I pull out 20-30 ticks on me and at least 100 on my dog.I don' t have lyme disease either does my dog.Lyme disease is from deer ticks which are so small they are hard to see.I have never seen one myself.I don' t really worry about them to much just check yourself when you take a shower.
