Pooches have been a part of the Google workplace culture for years. The search giant, in fact, makes it clear in its code of conduct that it's a company that prefers dogs to cats and suggests employees leave feline friends at home. There are rules, though. Employees have to get approval from their managers and work neighbors to make sure everyone's OK with it. Dogs aren't allowed in meetings, break areas or on the sand volleyball court. And there's a one-strike policy for messes or aggressive behavior.
