Hello I have a dwarf rabbit he is around 6 month old ,he eat and drink water and act normal but once I picked him up and put him back on the ground he started to move shake a little bit his head and move hos hand like he couldn’t control it but it was for only 10 or 15 second and he went back to normal also he hate being picked up and get stressed easily so I thought it could be because of stress,I went to the vet and the vet checked his ears and he didn’t had infection or anything,but now he did the head shake again two time again what cause that ?could it be because he get stressed because he get scared of anything easily of every little noise
