Ice melts are harmful
in two ways: they may irritate a
dog's paws, and if a
dog happens to licks his feet after walking on ice melt, the residue may
trigger drooling, nausea and
vomiting, according to veterinarian Debra Primovic.
Another main
trigger is the involuntary movement of the hairlike cilia
in the respiratory tract which remove foreign matter from the air before it gets into the lungs, but other underlying causes can include mucous irritation, obstruction of the nasal passage, inflammation, excess nasal discharge or secretion, pneumonia, chronic
vomiting, GI disease, and nasal tumors and dental diseases
in older
dogs.
