Roundworm-Dirofilaria (Heartworm)

Treatment of heartworm (if heartworm doesn’t kill the animal first) is with diethylcarbamazine or Ivermectin. Prevention is really important and it’s also really important to get your dog tested for heartworm BEFORE giving it the preventative because if the wormer or preventative kills the worms off too quickly, the animal may have an anaphylactic reaction and die. It’s a bad deal.
