Just realised I'd not mentioned on here, but Mango is bullying Ollie when we aren't about. Over food again, but worse if we aren't there. Heard a loud noise yesterday morning while on the toilet, luckily my brother was up and went to see what was happening. Found ollie cowering under the desk shaking with a lot of saliva on him, Mango nearby with a pack of buffalo ears she'd managed to climb up and steal (god knows how, camera doesn't cover that point, but they were too high for her?!?!?). Seems she'd pulled them down then gone for ollie when he approached, poor thing was scared of her all day. Took til lunch time before he'd go near her again, but stayed very wary. He literally climbed into my arms rather than walk past her, and he's not a dog that likes being picked up. I wonder if some of his aggression is taking out frustration?
