Hiccups are normal for dogs. They may be caused by catching cold, eating too fast, indigestion, etc. You can feed some probiotics to regulate the gastrointestinal tract. If hiccups persist, it may be a disease in the body, and the pet must be sent to the pet in time. During hospital examination and treatment, you should pay attention to your dog's diet. Choose small and frequent meals to help your dog's intestinal digestion. Do not feed foods with high oil and salt content that are not good for your dog's health.
