So I have my two girl rabbits, who are sisters, they share a cage and play area. The one in question, Spaz, has lionhead fur, but they are all lop/lionhead mixes. Today I went to change their water and noticed Spaz has some fur missing off her forehead. I DO know her sister DOES lick her a lot, The missing fur really just looks like too much licking/rubbing on Dora's part, as opposed to fur being ripped out. Dora has never shown any violence or meanness towards Spaz. Could the missing fur just be Spaz going bald, or just too much rubbing and licking from her sister, or what?
