Depending on the parasite, deworming typically​requires two (or more) treatments. The second treatment should be administered 2-3 weeks after the first. Submit a stool sample to your veterinarian to diagnose the specific parasites so the appropriate medication can be dispensed and to confirm clearance. If there are still parasites, repeat the deworming and then place Olivia on a monthly preventative such as HeartGard or Sentinel.
