Cardiac Issues in Dogs

Cost of Treatment: $1,100 to $20,000

Which Cardiac Issues are Dogs Prone to?

  • valve malformations known as dysplasia
  • valve narrowing known as stenosis
  • septal defects, which are abnormal openings between the dog’s heart chambers
  • patent ductus arteriosus, where one of the heart vessels does not close properly
  • a congenital condition that involves a combination of four heart defects known as tetralogy of fallot.

ALERT: Many dogs born with severe heart defects may not live beyond one year of age.


Treatments can range from long-term medication to open-heart surgery, depending on the specific cardiac disorder and the severity of that disorder.
