The Miniature Dachshund, also known as the wiener dog, has become one of the most popular breeds due to its unique size and big personality. These pups are iconic for their little legs and long back body. They grow as tall as 6 inches and up to 12 pounds. Mini Dachshunds have three types of coats: smooth or shorthaired, wirehaired, and longhaired. These intelligent, vigilant dogs may be small, but they have a big bark! Mini Dachshunds are great for a family with older children looking for a pet.
