I have 2.5 kg bunny with snuffles. We are on baytril treatment so far it got better but not cured completely. So i want to try echinacea i heard so many good things about it. I want to break the capsule and put the powder inside to his water. One capsule has 250 mg extract per capsule. Do you have any suggestion how much water i need for a capsule? How mg extract is okay for him?
