Daffodils eyelids are still pale, so I have been worming her with oral ivermectin made for horses, today was the day to do the second dose 10 days following the first. I rolled my ring out to the correct dosage and shot it in her mouth but for some reason the ring didn't stop the plunger this time as it should. So I gave her 3/4 of a horse sized dose. I usually give her a 1/4 horse sized dose at a time. Should I be worried? I have heard it is much better to overdose a goat on wormers than underdose but that is a huge dose for such a little girl.
