Hi there, I have noticed that my guinea pig is losing hair on the back end of his body (on the top side, but near the butt). He still has hair in this area, but it is just very thin. I noticed it a month or so ago, but I didn't think much about it. Today I noticed some flakes on his hairs in the area. I went to grab at the hairs with dandruff and those hairs just came off his body with an easy tug.
Does he have a problem, or is this normal? Any help would help. Thanks.
