Ordered Heartgard pills for my two dogs from 1-800-petmeds. They contacted Blackwood Animal Hospital to make sure that both does had been tested (which they both were together, both came back negative for heartworms), and as anyone who has dealt with 1-800-petmeds before, know that that is how they operate. Find with me, no problem there, but what I don't understand is why thye approved one dog electronically, but for the other want me to come in and pick up a written script to snail-mail to 1-800-petmeds. Is this RETARDED or what.
