Hey guys! So Quinn has this rather large bald spot on his side (I'm assuming it's mites since I've dealt with them before Although I've never had them get bald spots.) Anyway Quinn and Potter are 3 months old (born sept. 25) and Vincent is 4 months is it okay to use ivermectin on them being so young? I used it for Thor and Loki but they were older. How much should I give them (I'm thinking about 1/4 a grain of rice). I used to give loki (who was unusually large) a whole grain and thor half a grain and they're smaller than thor was then so I figure 1/4 sounded right. What do you guys think?
