A fully grown miniature dachshund is typically 5 to 7 inches tall and weighs 8 to 11 pounds. They are usually fully grown at around 12 months of age, but they can continue to gain weight until they are about 18 months old. 

Miniature dachshunds are one of two sizes of dachshunds, the other being the standard dachshund, which is 8 to 9 inches tall and weighs 16 to 32 pounds. Both miniature and standard dachshunds are low to the ground and have well-defined muscles. 

Miniature dachshunds are also known as doxies or sausage dogs. They are affectionate, friendly, and alert, and can have a lifespan of 12 to 16 years.
