Frequent episodes of diaphragmatic spasms, commonly observed in young canines, involve involuntary contractions of the diaphragm muscle. These contractions cause a sudden intake of air, which is abruptly halted by the closure of the glottis, producing the characteristic “hic” sound. These occurrences are generally considered benign in puppies.
Understanding the physiological mechanisms behind these spasms can alleviate owner concerns. These spasms are typically harmless and tend to resolve on their own as the puppy matures. The episodes often represent a normal developmental phase, and their prevalence usually diminishes with age as the puppy’s nervous system fully develops.
