If you are a puppy owner, you probably have heard your dog having hiccups. It is fairly common among young dogs. But what causes them? And is it normal in adult dogs?
Hiccups are caused by the spasmic contraction of a diaphragm – membrane that separates thoracic and abdominal caves. The innervation runs through the neck and inner organs to the diaphragm and assists in breathing. If those nerves are immature (as in puppies) or are irritated (as in adults) hiccups occur.
Hiccups in puppies
As your puppy’s anatomy is still developing, until he or she reaches 6 months hiccups are fairly common and normally not a reason for concern. If your puppy is having a longer bout of hiccups, you can place him on the back and roll gently from side to side a couple of times. Sometimes it is enough for the spasm to stop.
Hiccups in adults
Dogs of six months and older rarely get hiccups as their nervous system
What could cause hiccups? If you start noting down and recording the situations when it happens it might help to find the triggering factor. You should write down what your dog was doing and take a video. Some people might falsely name reverse sneezing or focal seizures as hiccups. So any extra information will be helpful to your veterinary doctor. Any mass or anatomical change causing pressure on the diaphragm or nervous tissue can trigger the hiccup bouts. Therefore your veterinary doctor might order a chest x-ray and abdominal ultrasound examinations. Electrolyte abnormalities from chronic vomiting or diarrhoea, kidney disease or lesions in the central nervous system can also result in the spasms.
If the hiccups are occasional, you should not worry, we adults get them too. However, whenever, you observe an unusual behaviour for your dog that tends to repeat itself, consult your veterinary doctor.
