You are very welcome. Sometimes when dogs cough up or spit up when walking fast it's because they are pulling on the leash. Many times the trachea will be sensitive for another reason (like a mild infection, allergies or air contamination) and the pressure from the pulling triggers the coughing.
If this does not appear to be the case, his stomach could be upset and the excessive movement from moving faster could be inciting the vomiting. This would be very concerning for a blockage in the stomach or severe irritation to the stomach or esophagus. I recommend to play it safe and have Kaju examined by the veterinarian to get a better idea of what exactly is happening. Best of luck.
