Sas, this is really neither here nor there but you mentioned flora...

When my mini lop was ill with a hind gut infection, my bun-savy vet told me I could feed her about a tablespoon of pinacolada, plain, or pineapple yogurt, daily. (Not the fat-free stuff - the regular kind.) While that really has nothing to do with sinuses, it might be a viable option for disgusing meds and/or adding varity to Denver's palate.

Pedialyte is an option, too, if you're concerned about dehydration from the diarrhea. However, Sophie wouldn't touch the stuff... I took a sip and can't say I blame her! YUCK!!


Good luck with the bun; keeping you guys in my thoughts!
