According to my experience, just relax slowly. When feeding these days, feed less and drink more water, and it will get better gradually.
No matter whether people or dogs burp. Most of the causes are not easy to find out, and generally it will not affect health. Burping is more or less related to the content of diet. Eating food that is easy to produce gas may cause it, but it is not absolutely certain.
When people burp, gulping water or holding their breath for a few seconds will help to stop burping, but when dogs burp, it is difficult to ask them to do so, so the owner might as well pat the dog on the back and massage his stomach, so as to stop burping earlier.
unless the dog burps for more than a day, it is necessary to consult a doctor.
