Not saying you lied about her having lime "Disease". Just that you should have been a little more competent at checking yourselves. If you had enough ticks around that it took 3 weeks somethings wrong. Usually they're there for no more than an hour or two or overnight and they're full and drop off. I'm with Rob. She may have caught Lime Disease alright, but the 3 week fumigation was NOT ticks, probably chiggers.
