I noticed my dwarf hamster looked a little less in fur towards the hind legs and rear. I didn't think much of it, but later, I checked again, and he's lost even more fur, and there are small dots of red on the skin. He lives with 2 other male dwarf hamsters, and they fight occasionally, but it's normally the other 2 hamsters that often fight, not him. But he's the one that looks really unhealthy.
Please, does anyone know what I can do to help him? :(
