A few days ago, I’ve noticed that my little dwarf girl (Waffuls) had some fur missing on her face. I took a look at it, and nothing seemed “bad” about it, just a bald spot. Yesterday I noticed it was due to the other rabbit licking/biting/grooming her face obsessively. I’ve tried shooing him away every time I see him doing it now, but it’s so often (literally like every few minutes) that it’s becoming hard to manage. The odd thing is, that she is the dominant one, and it seems like she’s enjoying it? She will run up to him to have him do it to her. I wouldn’t mind so much the bald spot, but this morning I noticed it’s actually making her bleed and scab.
I normally let them run around together, but after seeing that this morning, I’ve separated them; and that makes me feel bad.
I’m not sure what to do at this point. Has anyone else experienced this kind of behavior or this issue?

Thank you!
