Pericardial effusion in dogs refers to the abnormal accumulation of fluid in the pericardial sac, the thin membrane that surrounds the heart. While it can occur secondary to trauma, infection, or systemic illness, in many cases, the cause remains idiopathic, especially in large-breed dogs. Regardless...
Heart disease in dogs and cats can range from mild and slowly progressive to sudden and life-threatening. While many cardiac conditions are managed long-term with medications and lifestyle adjustments, certain warning signs should never be ignored. Recognizing these red flags early can be the difference...
Complex congenital heart diseases involve multiple defects occurring together, leading to severe circulatory disturbances that often require early intervention. These conditions typically result in cyanosis (blue-tinged gums), exercise intolerance, and right-to-left blood shunting, which reduces oxygen delivery to the body. Tetralogy of Fallot (TOF) in Dogs What...
If you've ever noticed your dog tiring more quickly than usual or developing a swollen belly with no clear explanation, you might wonder if something more serious is going on beneath the surface. In some dogs, especially breeds like Labrador Retrievers or Boxers, these signs...
Atrial Septal Defect (ASD) in Dogs What is ASD? Atrial septal defects (ASD) in dogs are abnormal openings in the septum that separates the left and right atria. This allows oxygen-rich blood (from the left atrium) to mix with oxygen-poor blood (in the right atrium), increasing blood...
If your dog has been diagnosed with a heart murmur or is showing signs like fatigue, fainting, or trouble during exercise, pulmonic stenosis could be the underlying cause. This congenital heart condition is one of the most common in dogs—and while it can be mild...
Patent ductus arteriosus (PDA) is one of the most frequently diagnosed congenital heart defects in dogs—and one of the few that can be completely corrected with timely treatment. While this condition starts as a simple failure of a fetal blood vessel to close, its consequences...
A seemingly harmless heart murmur could be the first sign of a life-threatening condition called subaortic stenosis in dogs. Subaortic stenosis (SAS) is a serious congenital heart condition that primarily affects large and giant dog breeds. Though it may go unnoticed at first, early signs—like...
