I think most animals don't have language. And if they do, it extremely limited. They simply don't need to have names for everything because their lives are so simple.
If any animals have an advanced language like we do I think it might be whales and dolphins.
Edit: Just researched the neurobiology of dolphins and and whales. Totally blown away!
Not only do they use different whistle pitches for names of different whales/dolphins in their pods, but they can also communicate with one another 20x faster than humans can!! They do this by projecting auditory images to one another. No need to spend minutes describing exactly what the mean, with the way they communicate every detail of an object is sent through one sonar wave.
