Dogs use their noses for smelling like people do, although a dog's sense of smell is much better than a human's. They can differentiate the scent of many different dogs when just smelling a single tree and can detect a scent from much further away than humans and many other animals.

No, dogs cannot sense the future. They can, however, pick up on some sensations that are outside of a human's perception and react to those sensations in advance of a human's awareness of an impending crisis. Typically these sensations are low or high frequency sounds, shifts in scents and low frequency vibrations.
Some dogs will howl at any high pitched frequency because their ears are far more sensitive than human ears.
Dogs sniff things because this is how they find out about their environment. By smelling the telephone at the end of your street they can tell how many male dogs have peed on it. They can also tell what other kinds of animals have been in the area by smelling.
I'm not exactly sure, but, I think that wolves have better smelling abilities than dogs because, they are more wild and really need to use their senses to hunt prey and to survive. Also, it depends which dog it is and what breed it is, some dogs have better smelling abilities than others.
Yes, although whether or not a human could produce such a scream is debatable. Dogs have hearing that extends into a higher frequency than a human's hearing range, which is why dog whistles work like they do.
