A relativistic definition of intelligence: I think it would be hard to do, e.g. your example would make dogs one of the most intelligent species on Earth, relative to humans, much smarter then chimpanzees. To be frank I find the whole concept of intelligence to be more problematic then its worth.

That said, if we are ever able to establish communication with a species other then our own that evolved elsewhere in the galaxy, intelligence might at that point become an outdated concept.
