I posted a few weeks ago about my Charlie rabbit possibly having mites, anyway i took him to the vets and they gave him Xeno 450 to put on, two tubes first then another two tubes two weeks after. He has now had the second course of treatment but there is no sign of improvement. He still has the bald patch and the flaky dandruff. Should i have seen signs of improvement by now? I am concerned as he we are due to go on holiday in three weeks and he is going into boarding. I want this cleared up so he dosent infect the other rabbits or cannot go at all Advice needed, thanks
