Despite the cat's obvious popularity in Gotham City, Urbanhound is a dog's best friend. Dubbed "the urban dog's ultimate survival guide," Urbanhound is a website totally devoted to dogs (and their owners) in NYC, Chicago and San Francisco.

Extremely well organized, Urbanhound has messageboards, dog run listings, an online Vet and trainer, a store, service listings and even a page for you to upload your own hound pic and details. In short, everything from finding a new dog to taking care of an old, sick one is covered here. (Thanks, Caroline!)
