prince is sneezing ALOT, like allllllll the time. short lil sneezes but when hes excited theyre much bigger sneezes! and sniffling.. i thought maybe it was something in the house? my perfume? theres no mucus or cough though. hes been to the vet and hes on antibiotics bc this could be the onset of a cold. this was his 2nd day of the medicine. could this just be allergies? then tonight i heard him hacking for a few seconds. or maybe reverse sneeze? clearing his throat? should i be worried.
