Why Dog Burping Happens. There are some dogsthat burp because they’re allergic to their food. You might want to consider talking to your vet about having your dog tested for allergies, and change his routine if necessary. The more likely cause, however, is that your dog is simply eating or drinking too fast.

Does this happen regularly to your pup? Does he eat and then belch? Burping is common in dogs. Most of the time the bodily function is harmless. Sometimes it may be a cause for concern.

Envision the scene. It’s early and your dog finished his morning business. You fill his food bowl with breakfast and he scarfs down the kibble. A few minutes later the sound is unmistakable: your dog burps.
