Diaphragmatic Hernia in Dogs
Diaphragmatic Hernia is a high-severity respiratory condition that can affect dogs of all ages and breeds. A diaphragmatic hernia occurs when a tear in the diaphragm allows abdominal organs (liver, stomach, intestine) to herniate into the thoracic cavity, compressing the lungs and causing respiratory distress. May be congenital or traumatic. It is documented across 2 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Any age (trauma) or birth (congenital). Early signs to watch for include respiratory distress, muffled heart sounds, reduced lung sounds on one side, and reduced appetite. When treatment is required, costs are estimated at £2,000-£5,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
