"Do YOU hear a heart murmur?" Whether you are hoping to breed your dog or have adopted a new puppy, auscultation by a boarded cardiologist may detect important heart sounds which may merit further diagnostics.



Meet with your board certified cardiologist for a comprehensive examination of your pet's cardiovascular health.



  • Management of heart disease

  • Management of heart failure

  • Pericardiocentesis: a delicate, potentially life-saving procedure which removes fluid from the sac around the heart.

  • Thoracocentesis: a delicate, potentially life-saving procedure which removes fluid from around the lungs.

  • Abdominocentesis: removes the accumulation of fluid from the belly.

  • Arrhythmia therapy offers emergent care for animals facing life-threatening arrhythmias.



An echocardiogram is an ultrasound of your pet's heart. It enables the cardiologist to view valvular, muscular, and functional aspects of your pet's heart. It evaluates at the heart muscle, the chambers, the function, and the flow of blood through the heart and in/out of the lungs.



A cardiologist is the specialist you refer to when your pet requires a thoracic (lung) ultrasound. This diagnostic aids in the diagnosis of thoracic abnormalities not readily diagnosed on radiographs. A cardiologist can perform aspirates of pulmonary (lung) lesions which aid in diagnostics.



An electrocardiogram, or ECG/EKG monitors the electrical conductivity in the heart of your pet. This tool diagnoses arrhythmias,  and is used to diagnose electrical disturbances in you pet's heart.



A board certified cardiologist offers the interpretation of a specialist regarding heart enlargement, heart failure, and other abnormalities regarding the heart and lungs on radiograph.



A holter monitor is a noninvasive device  your dog or cat wears for 24-48 hours which helps to diagnosis arrhythmias which may not be detectable with brief ECGs. This is also used in pre-breeding screening for breeds such as the Doberman Pinscher and Boxer
