A 1 year + male dog was diagnosed in my clinic,he was said to have the following symptoms; Sneezing Loss of appetite (anorexia) mucus discharge Decreased air flow (stuffy nose) in one nasal passage Reverse sneezing. so there was a bit of argument whether it's rhinitis or sinusitis between the vet students in the clinic. So please help clarify,also include the causes,prevention and treatment. Thank you
