Hello! A cough like the one you're describing in a little dog like Lace, I'd be worried about a collapsing trachea or congestive heart failure - both conditions are very common in little dogs and can cause dramatic coughs. Other possibilities would be kennel cough, pneumonia, allergies, and parasites. Hairballs are pretty uncommon in dogs, though bronchitis is possible if this were an allergic issue - but allergic coughs usually start at a younger age. With such dramatic onset, I definitely recommend having Lace seen by a vet, and anticipate they'll take chest x-rays to evaluate what's going on with her heart and lungs. Hope this helps.
