Yorkie Heart Problems
Yorkshire Terriers are susceptible to heart problems. In fact, heart failure is the main cause of death in older Yorkshire Terriers. And this condition is exacerbated in Teacup Yorkshire Terriers.
Two of the conditions they are prone to are patent ductus arteriosus (PDA) and mitral valve disease. PDA is caused by a small vessel in the heart that didn’t close up after birth. This causes fluid to build up and puts a strain on the heart. Dogs with PDA have a specific type of heart murmur. It can often be repaired with heart surgery once detected. Signs of this condition include coughing, shortness of breath, fatigue during exercise, and weakness in the hind legs.
Mitral valve disease is more common in older dogs. It is the result of weakened heart valves that allow a backflow of blood. This puts a strain on the heart. This disease can often be managed with medication and annual heart testing. Breeders should have proof of thorough cardiac evaluations of both parents and not breed a dog with PDA or mitral valve disease.
