Atrial Septal Defect in Dogs
If your dog has atrial septal defect, it has a defect or hole in the wall separating the left and right atrium of the heart. Heart consists of four chambers, and the left and right atria are the two of them. The walls between the rooms of the heart muscle called the septal. When the dog is still embryonic heart consists of a single tube. This fund will then gradually separated into four chambers before the puppy is born. Handicapped can grow at different steps of the process, and the result can be small or large defects in the atrial septal dog heart. Precise effects in dogs will depend on how big the defective and exactly where he is.

If your dog has a large atrium septal defect, the situation is worse because of such defects will cause abnormal blood flow from the left side of the heart through the defect and into the right side. This makes a bigger workload for the right side of the heart, and this in turn can cause the right side of the heart fails to be shut down without seeking treatment. Dogs with large atrial septal defect may develop symptoms such as fainting, exercise intolerance, difficulty breathing, fainting, abnormal heart rhythm, and swelling. Right side heart failure may cause sudden death. A dog only with small atrial septal defect on the other hand will usually reach normal age for his breed.
