The Chiweenie — known affectionately as the Mexican Hot Dog, the German Taco, and the Weeniehuahua — is one of the most American of companion dog combinations: two of the US's most popular small breeds, the Chihuahua and the Dachshund, producing a tiny, feisty, enormously entertaining little dog with one of the most memorable nicknames in the designer dog world. The cross appears frequently in American shelters (often the result of unplanned litters between family pets) and is produced intentionally by breeders for a market that specifically appreciates the combination's compact apartment size, minimal grooming, and outsized personality. At 5-12 pounds and 6-10 inches tall, the Chiweenie is literally a purse dog — though it will insist on being treated as anything but.
