I have been a Basenji owner for the past 4.5 years. As of 2-3 months ago I noticed from time to time that my Basenji will be “half hiccuping”, if you may, while whining and being restless. When I take him outside he stops whining but begins to gorge on grass. Sometimes he will vomit and other times he will not. Does anyone know what could be bothering the little guy? He will not settle down when this happens and regardless of how long we are outside, once we get home he’ll want to go back out again in a few minutes time.
