Unlike exposure to other toxins, many Agent Orange symptoms tend to take several years to decades to present, and can cause a host of health issues. Initial symptoms tend to include common side effects found with many other illnesses, as well as neurological and psychological problems.
Heavy breathing or panting. Most dogs will pant from time to time because they are stressed or excited, but when dogs pant for no apparent reason and the panting becomes excessive, this can definitely be a sign that a dog is experiencing pain.
However, excessive panting can be a sign of illness, heat stroke or stress. It's important for you to know how much your dog usually pants so you can address the issue if panting becomes excessive. Heat Stroke. Each dog is a little different in how much he pants during and after exercise. Knowing your dog will help you identify heat stroke, which often occurs during a tough workout or exercise during hot weather. If your dog is panting for longer than 10 minutes after your exercise, contact your veterinarian. Other symptoms of heat stroke include excessive drooling, red tongue and gums, vomiting, dizziness, lethargy and seizure. To treat heat stroke, make sure your dog is drinking water.
