The act of snorting is performed thus: - The dog stands still, holds up his head with nose pointed forwards and upwards, draws in air through the nostrils, and instantly expels it in a succession of loud, spasmodic snorts, which are not pleasant to hear, and which are sometimes continued till the dog staggers and falls down. These snorts sometimes alternate with fits of sneezing. They seem to have for their object the expulsion of some foreign body lodged in the nose, such as a worm,* blade of grass, etc. This snorting sound may likewise accompany cold in the head, and then is expulsive of accumulated mucus, and is occasionally symptomatic of nasal polypus.

The snorting will, of course, cease on the removal of its cause.
