Since its Thanksgiving, the vets are closed and I need help identifying some spots on my horse. About a week ago I noticed that my 13 year old gelding had little bumps all over his body. At first they looked like mosquito bites but now they are a little bigger. The spots are all over his body and crusty but you cannot see them in pictures because the hair is still covering them. Where the scabby spots are located along his mane, the hair has started to come out. Im wondering what this may be and if this could be the reason to why he cannot keep weight on?
