Understanding Heart Attacks in Dogs
While heart attacks in dogs are relatively rare compared to humans, they represent a serious and potentially life-threatening emergency that requires immediate veterinary attention. Unlike human heart attacks, which typically result from coronary artery disease, canine heart attacks usually occur due to blood clots, infections, or other systemic issues that obstruct blood flow to the heart muscle.
Understanding the unique nature of heart attacks in dogs is crucial for every pet owner, as quick recognition of symptoms and prompt medical intervention can mean the difference between life and death for affected animals.
Common Causes of Canine Heart Attacks
Several underlying conditions can trigger a heart attack in dogs:
- Blood clots (thromboembolism)
- Bacterial infections affecting the heart
- Tumors near cardiac blood vessels
- Severe hypothyroidism
- Inflammatory conditions like vasculitis
- Nephrotic syndrome
- Rare cases of atherosclerosis

Recognizing the symptoms of a heart attack in dogs requires careful attention to sudden changes in your pet's behavior and physical condition. Key warning signs include:
Immediate Emergency Signs
