HI Thanks for posting your query. Its not the question of whether you like or dislike to give him antibiotics . If it is really an ear infection with Pus accumulation then yes he has to be put on Antibiotics else it may turn into some serious infection even spreading to face or Brain . If at all you doubt the diagnosis done by that doctor take a second opinion and if the second doctor too opines the same kindly get him the antibiotics. Hope this information was useful to you. Any clarification feel free to ask .
