PS: You can go to a vet and get Imizol overnighted to you from any university with a vet school. Remember, you do NOT have to "prove" your dog has babesia (i.e., wait for test results) to use Imizol legally, so don't let your vet say you "have to wait" for a blood test to give you the drug. The Imizol label specifically says to use the drug for SYMPTOMS of babesia too (lethargy, anemia, fever, etc.), precisely because it can be tough to detect, so INSIST he read the Imizol label online and just get that drug overnighted now.
