lymes again

So here in PA where the temp never went below 40 degrees all winter has a terrible tick problem even in the best of times. I am so hesistant to use the pesticides on the dogs but am forced to make a decision. Either use it or worry about them getting sick. Well, I compromise by just using it for the warmest months and very sparingly. But we still have some of them get sick and once they do, they are more susceptible to getting sick over and over. Well, this seems to be happening to my Fiona. Back in December when we returned from Eukanuba she was in extreme pain and had some paralysis in her face. We put her on the doxy and she cleared up. She still had a bit of facial paralysis but better. THat was until yesterday when she exhibited the tell tale signes. Stiffness in the leg, pain in her neck. So back on the doxy for 3weeks and we hope there is no permanent damage.
