The Dachshund. Originally bred to scent, chase, and flush out burrow-dwelling animals this is a clever, lively, & playful breed, which comes in a variety of sizes/coat-types. They are well known for being stubborn, making them a challenge to train. If not trained with consistency they will develop bad habits & become spoiled. Dachshunds are known for their devotion and loyalty to their owners, but usually aren't a great choice for children unless dog & child alike are well trained/behaved.
