My doe has a growing number of spots of missing hair. The areas are round, between a dime and nickel in size. A small, eraser-sized, dry, thin scab in the center of some, some are just bare in the center. No raised or scabby rings. Hair around the circles has flakes of skin (dandruff). These spots are located below her hip and her rib area but not in the normal "fence-rubbed" areas. The area below her hip has 4 spots clustered together. None on her topline, head, neck or face. Before I treat her, I'd like some suggestions. I was thinking a SQ dose of Ivomec but want to confirm the dosage. Also a good dusting for all five goats? I have Ivomec 1% injectable, Ivomec Plus, antifungal creams, lice and mite dust, DE, Adams Flea and Tick spray, etc.
