Q: Do I still have to worry about Lyme disease, even in the winter? A:Actually, even though the ground is frozen, ticks can live on a host in a warm place through the winter.

A notion struck Betsy Sigmon on the way to the hospital to tend to her 13-year-old son Jason.

Ticks can be considered by many as the worst external parasite which can be found on your dog.

I am ticked, well actually thrilled. Learning about Lyme disease from Robert S. Lane Ph.D., professor of medical entomology at U.C. Berkeley, is like having Jimi Hendrix give you guitar lessons.
