How to diagnose heart conditions in doberman pinschers
Monitor for respiratory distress.
One of the symptoms of heart disease includes different respiratory problems. These respiratory problems occur because the heart has trouble pumping oxygen to the body and your dog's heart has to work harder to get blood flowing throughout the body.
Your dog may exhibit an unusual shortness of breath, rapid breathing, or labored breathing. If these symptoms persist more than a few days, you should take your dog to the vet.
