We started using Garlic Barrier on my wife's dairy goats just a couple weeks ago. We just mixed it with water in a oral syringe thinking we were going to have to force it down them as potent as it smelled but they drank it right down. How long was before you noticed a change in eyelid color and how often would you recommend the 3 times 4 or 5 days apart dosage? Somewhere I read to just dose them once every 2 months but we haven't really seen any results yet
