I just got two guinea pigs at the start of this year. One of them now has a bald spot and lots of dandruff around his rear and the other one has an open wound behind his little ear. They are not very old at all and I have no idea what to do other than google it. They are still eating and drinking just fine. Itching occasionally. What should I do? Is there a way to tell if mites or fungus?
Thanks
