Best for: Allergy sufferers and active athletes who crave a partner across nearly any type of terrain (or body of water.)

Don't be fooled by poodles' fussy looks – they're one of the most intelligent, athletic, and adaptable breeds. Powerful legs give them serious hopping and distance-running abilities. Plus, their shed-proof, hypoallergenic coat means you won't need a Benadryl drip just to be near one.
