The Chiweenie is a Chihuahua and Dachshund cross, usually with a miniature Dachshund, first bred deliberately in North America in the late 1990s. It isn't a standardized breed, so size, coat and build vary. Most weigh 5 to 12 pounds, and some have the long back and short legs of a Dachshund while others look more like a sturdy Chihuahua.
In Brooklyn, the compact size suits apartment life, and many Chiweenies bond closely with one or two people. They tend to be alert and vocal, which matters in buildings with thin walls. Expect to put time into treat-based training, protect the back from hard jumps, and brush teeth regularly. Coats are usually short and easy to care for.
