bunny hair loss

Question
why is my bunny losing a lot of hair?  does he needs vitamins

Answer
Dear Adriana,

Please read this for all the most common causes and treatments of abnormal hair loss in rabbits:

It's not likely anything to do with vitamins, but more likely mites or other ectoparasite.  Please find a good rabbit vet here:

who can properly diagnose and treat the problem.
