if he is still young, he could be alop. when i got daisy, a mini lop, she had stand up ears,then she seemed to be able to switch them around and now they are downall the time. she is a pure mini lop and i was told by herbreeder that as the ears grow, they get heavier and then start to lop,although her ears are smaller then sage, her mini lop husband, so idon't know about that. anyway, she used to have the same earissue, but now they hang all the time.
