In my experience gh’s drop weight (muscle mass) like a stone while on pred. Systemic side effects are typically much much lower with budesonide.Forgive me but, did you say you did check rads already? I’ve never heard of a dog coughing from ibd.
Ok-a bit off track here but, gotta ask-who intubated your dog? Often it’s the techs job-if he or she wasn’t being careful it could be missed. Also, if propofol was used it could have been your dog wasn’t taking breaths at the time.
