The Chipoo — Chi-Poo, Poochi, Wapoo, or Choodle depending on the American designer dog community being consulted — is a very small dog with a personality that systematically ignores its own size. The Chihuahua parent contributes the same characteristics that make the purebred version one of America's most popular toy breeds: fierce loyalty to one person, a watchdog instinct grossly disproportionate to its stature, and a terrier-adjacent boldness that approaches strangers with calculation rather than enthusiasm. The Toy Poodle parent contributes quick intelligence, near-zero shedding, and the training responsiveness that tempers the Chihuahua's more challenging qualities. The result is a tiny, allergy-friendly companion with a personality that American urban apartment dwellers frequently describe as exactly sized for their lifestyle.
