Alright, so by the end of the summer, I'll be moving to Burleson, TX... I'm guessing that's central? Well I hear that the flea and heartworm situation in TX is quite a bit more extreme than it is here (where it's pretty uncommon). How do you guys in TX deal with fleas? Do you use chemicals? Has anyone been able to get away with natural prevention/remedies? What about heartworm?
