It shouldn't come as a shock to anyone that Nintendogs is a cute game. When a game is based around puppies, it's hard not to have the game look cute unless, of course, you're pitting the puppies in barbed-wire, steel cage death matches. Then again, puppies could probably make that grim scene look cute. What should come as a surprise is just how good the game looks. The DS is not a system that has been known for it's graphics, least of all it's 3D ones. However, Nintendogs manages to pull off a really clean looking visual style that works within the confines of the DS's capabilities which end up making it look like it's on a much powerful system. All of the dogs are really expressive and animate very smoothly. Animations are especially neat after seeing the number of animations that are included in the game. This is especially apparent when you begin to teach your dog some of the more advanced tricks.
Sound isn't much of an issue. Other than your dog barking and the random squeak of a toy, there really isn't that much noise going on in the game at all. A few brief pieces of music pop up from time to time, but overall Nintendogs is a pretty quiet game.
