At each TRIAD visit, your dog will have a basic physical during which the veterinarian who is seeing your dog will collect blood, urine, fur, and fecal samples using a Sample Kit provided by the Dog Aging Project. In addition, your dog will be seen by a veterinary cardiologist for an electrocardiogram and an echocardiogram. These procedures are non-invasive and can be performed while your dog is awake and comfortable.
