Thank you. Besides the baldspots behind thier ears has the hair loss resulted in any other bald areas? If so, where on the body?
Customer: replied 3 years ago.
No just a large area behind ear at neck area
Expert:  Dr. Jamie replied 3 years ago.
It is normal for guinea pigs to have hairless skin right behind thier ears. If there is no hairloss elsewhere or intense scratching/redness, I would say nothing is wrong.
The natural bald spots behind the ears of guinea pigs should normally be about 1cm in diameter and there is usually a few scattered hair present at the site. If he is an albino pig, then this might be even more pronounced.
