I know I will get a million different responces but will ask for opinions anyway. I normally worm my nigis with Safeguard for goats, per label instructions. I have noticed that the gums on one is looking a little pale and their coats seem a little rough. I talked to the guy at Southern States and he thinks that they have become resistant to the safeguard and recommended ivermectin. I have heard everything from double the dosage to quadruple the dosage. My goats weigh between 40 and 50 pounds. I bought the paste and now I'm not sure how to figure out how much to squirt out. 1 tube does 1250 pounds. should I dose them all at 100 pounds or 200? Double, triple or quadruple?
