I think it's impossible to compare human and animal intelligence because there's a "hard-coded" part to intelligence. I don't think being unable to understand human language says anything about the general intelligence of a non-human animal since humans are at least partially hard-wired to understand language. That pretty much precludes any animal from ever being able to "follow instructions", "speak", "understand logical problems", etcetera. Even if they would have the general intelligence to do the things we want them to do, it's very difficult to encode that information in a way that they would understand.
