Thank you everyone for the replies. I'm going to drop by her vet today (I have to check if it's open) and talk to him about having blood work done tomorrow morning and then having him get the Heartguard or Interceptor. They don't usually carry and heartworm preventive in the office. They have to special order it, since there's no heart worm here. The funny thing is that there is Leptospirosis here, but none in California where I live. I still don't do the Lepto shot anyway. But thank you everyone again for your help.
