Novel insights on the pattern of cough associated with tracheal collapse in griffon dogs

A prospective study was designed to test the hypothesis that the degree and location of tracheal collapse may influence its pattern of cough. Objective evaluation of cough was made in 45 dogs with tracheal collapse. The relationship between location and degree of collapse and cough was tested. Location of collapse did not have a significant effect on cough except for the moderate effect on the nature of cough (P=0.002; rs=0.45) while its degree had a significant effect (P
