If you work for a company that won't let you bring your dog to the office, then the next best thing is to bring Rover the doodles dog.
While Rover the doodles dog isn't anywhere near a real dog in terms of size or being alive, Rover will at least keep you company on your desk. Made using stainless steel wires that are connected at the joints with aluminum rivets, Rover the doodles dog has fully articulated joints letting you pose him in almost any position imaginable. A loyal companion, Rover can hold work items and notes, but you'll mostly be playing with him.
While real dogs are considered to be "man's best friend," Rover the doodles dog is the office worker's best friend and the best part is you don't have to clean up after him.
