Ivomec dosing HELP
I've read hundreds of posts on the subject of dosing dogs for heartworm prevention with 1% Ivomec solution. I'm more confused than ever. Some say dilute, some say don't dilute. I've noted dosages for undiluted 1% Ivomec for my 70 lb dog anywhere from .2cc to .7cc. Could someone please clear this up? Is it really that difficult to get a proper dosage or is this a kind of subjective topic?
