My 10 month old whippet has been sneezing and reverse sneezing since Thursday. I took him to the vet and they provided pain relief and are going to do a scope to see if they can find out if there is a blade of grass in there. Im a bit worried as he is often allowed out in the garden on his own to play whilst I’m working. Is this common for whippets or is this the best treatment?
