The royalty of dogs, His Highness the Poodle comes very close to being the top-dog on the list of the smartest dog breeds. Though up to this day, cynologists aren't sure whether this type of water dog (a dog that hunts waterfowl) originated from Germany or France, there's no doubt that they've won us over with their loyalty, intelligence, and gentleness. These puppies are versatile in sports, as working dogs and emotional support pets, but besides all that, they also have one trait that few other breeds have - they are known to be hypoallergenic. A quality that's undeniably important for those allergic to dog dander.
