If a Great Dane is hacking up the mucus this means they were coughing up mucus not vomiting. A Great Dane cough can be due to a respiratory infection (bacterial, viral, or fungal infection) or a medical condition.

Coughing can also be due to a Great Dane trying to get rid of something in their throat such as dust or a foreign object lodged in their throat.

Regurgitation on the other hand is different from vomiting. Unlike vomiting, regurgitation occurs suddenly without warning and a Great Dane throws up undigested contents in the same form they were swallowed whereas vomiting produces partly digested stomach contents.
