The dog is healthy but chews in vain

The dog is healthy but chews in vain. It may be that there is a problem with the dog’s mouth. Chewing in vain is a neurological symptom. Chewing in vain in dogs is usually because the dog has dog disease. Plague or epilepsy. If the dog is healthy and does not have canine distemper or epilepsy, then you should pay attention to check the dog's mouth. Check whether there are any foreign objects in the dog's mouth and whether the dog's mouth is inflamed.
