Using medications for intestinal parasites regularly can cause parasite resistance. We only deworm when we KNOW we need to. We check our animals health every month by getting our hands on them, checking their body score, coat condition, FAMACHA (eye) score and weighing them on our livestock scale. Performing fecals are the only way to 100% know that intestinal parasites are the culprit to poor condition.
