A Schweenie is a mixed breed dog, a cross between a Dachshund and a Shih Tzu. When it comes to weight and height, Schweenies can vary depending on the characteristics they inherit from each parent breed. On average, they typically weigh between 8 to 20 pounds and stand around 8 to 11 inches tall at the shoulder. However, individual variations can occur, so it's essential to consider the specific characteristics of the parents when estimating a Schweenie's size. Regular vet check-ups and a balanced diet can help maintain their health and well-being regardless of their size.
