Dogs hiccup. Dog hiccups, like humans, are caused by excessive gas accumulation in the gastrointestinal tract that needs to be discharged during the digestive process and gastrointestinal peristalsis.

It is normal for dogs to burp appropriately after meals, when they wake up, etc. However, if the dog burps frequently, or the exhaled gas has a strong sour smell and is accompanied by a large amount of farts, the dog may have indigestion or gastrointestinal flora imbalance, and it is recommended to seek medical treatment in time.

Why do dogs hiccup?

1. I ate too fast when I was too excited. When eating, a lot of air enters the stomach as the dog swallows. When the stomach is full, the excess air will be excreted through burping or farting in order to relieve pressure.

2. Hiccups are also related to the food the dog eats. If the dog eats some human food, or alkaline food reacts with gastric acid, a large amount of gas will also be produced.

3. Hiccups are also related to dog breeds. Examples include short-nosed dogs: Boston terriers, boxers, bulldogs and pugs. They have a unique head and face structure that makes it easier for them to bring gas inside while eating.

4. There are parasites in the body. If your dog burps frequently and appears tired, accompanied by diarrhea and vomiting, you should be wary of the presence of parasites in your dog's body. Worms such as heartworms or roundworms can cause damage to your dog's respiratory tract.

5. Stomach disease. If your dog has problems such as gastroenteritis, acid reflux, gastric volvulus, or bloating, it can cause your dog to burp frequently.

6. Breathing problems. If your dog keeps burping, sneezing or wheezing, it’s not a good sign. Your dog may be suffering from respiratory diseases such as pneumonia or bronchitis. These conditions will seriously endanger your dog’s life. You must take your dog with you. The dog seeks medical attention promptly.
