What to do in Death Valley if you don't have a truck?

The only problem with hiking is that they'll have a dog and dogs aren't allowed on the trails.

Ah, then Lance's list is very good. I try to only take my pups when I can get into the backcountry, and they can run around on the dirt roads (which is allowed, btw.) Racetrack is almost always 2wd accessible; titus canyon is hit or miss depending on the year. Usually ok. The visitors center there is actually very good, too. I spend a lot of time there when it's rainy or otherwise yucky to be outside.
