Dogs do not get laryngitis from barking, but can get the inflammation from strain, infection and even tumours.

This week's question comes to us from Linda Hall in British Columbia.  Dr. Peter Foley, an Associate Professor of Small Animal Internal Medicine at UPEI's Atlantic Veterinary College in Charlottetown says a dog's larynx is simply 'built' to allow it to bark for long periods of time without suffering any inflammation, or laryngitis.  However dogs can get laryngitis in other ways, including strain from a collar, infection or tumours.
