The Chiweenie is a Chihuahua and Dachshund mix, usually with a miniature Dachshund, that first appeared in North America in the late 1990s. It isn't a standardized breed, so looks vary widely. Many have the Dachshund's long back and short legs with the Chihuahua's big ears and rounded head, in short, long or occasionally wiry coats. Most weigh 5 to 12 pounds.
Chiweenies tend to be bold, loyal and lively, often bonding closely with a favorite person and speaking up about visitors and noises. Some are wary of strangers or rough handling. Adopters should plan on patient, reward-based training, careful back support and regular dental care, and remember that each dog's personality can differ from the typical mix.
