I have two guinea pigs and one is for sure the dominant one. The dominant one is named Zissou and she has started barbering the other pig named Scrump. It seems to be happening mostly at night and I have lots of toys and a steady supply of hay to try and keep them occupied. There are patches of hair missing from Scrump and she seems annoyed by the whole thing, but there is no broken skin or lesions or anything like that. Am I completely over reacting by being concerned by this? I have two different hideouts and I try and move Scrump to the hideout that Zissou is not in and Scrump runs back to Zissou! I really am just at my wits end and don’t want to be worried over something if there is nothing to worry about. Thank you in advance for your help.
