Poor Mimi! There are many different conditions that can cause coughing of white phlegm or saliva like this. Some possibilities would include a respiratory infection like kennel cough, heart disease, bronchitis, collapsing trachea, or pneumonia. Treatment will depend on what the underlying problem is, so it's important to get a diagnosis first. I would recommend taking Mimi to the vet for an exam as soon as you are able to. He/she can listen to her heart and lungs, and may also recommend chest x-rays or other testing if needed to help diagnose the problem.
