Panted, gasped (6)
I believe the answer is:
puffed
I believe this clue is a double definition.
'panted' is the first definition.
('puff' can be a synonym of 'pant')
'gasped' is the second definition.
('puff' can be a synonym of 'gasp')
(Other definitions for puffed that I've seen before include "Blew in short gusts" , "Out of breath" , "Panted, being breathless" , "Breathed hard from exertion, panted" , "Wheezed, being swollen" .)
