A veterinarian could give you a complete and honest assessment if you value your dog please make sure it gets the help it needs. No animal human or furry is normally short of breath that is not a normal state of any species
could be a bad case of worms .impacted colon or a intestinal problem. maybe a twisted stomach if its a big dog . where there stomach actually flips over inside of them . but that only happens with bigger breeds .like great danes or big shepreds
