Dogs having the abilty to detect health problems in humans?

If you are worried go get checked out. If the doctor asks why just tell him you haven't been feeling well or something. If it's nothing don't say anything about the dog if they do find something I would tell them. But your dog knows you are feeling well. It could be you are just getting a cold and he knows and he knows your stomach hurts. Dogs have all kinds of sixth senses. They can figure out alot of things. Health problems or emotional problems. They know they sense it get checked out.
