I was reading the label of my dewormer (Ivermectin by Bimectin) and (as with all horses) you dose by weight. I have always just guessed at horses' weights (bad bad, I know) and I was just wondering if there are any adverse effects of giving a horse too much ivermectin dewormer? If so, how much more than the recommended amount would be considered an overdose? What will happen?
Any information would be wonderful!
