It is Enrofloxacin 20mg/cc and he is 630grams he gets 0.20cc once every 24 hrs..not sure if that is right being my vet has giving to same dose to every rat I have gotten antibiotics for even though they are different weights...rose being 266grams and has the same dose....He is gasping for air now so not sure how much longer he has....I tried steam and it made him freak out so I cut that and he had the benadryl which seem to work for a short time....Not sure what to do now for him.It is crushing my soul to watch him suffer but he doesn't want me to hold him, he just wants to hide under his blanket.
