Although every dog is different, Dachshund terrier mixes are generally very energetic, intelligent and fearless. Dachshund terrier mixes are often referred to as toy rat doxies.
Any dog that is part terrier will be curious and energetic. It will need plenty of exercise to keep from getting into trouble, and when mixed with a mild-mannered Dachshund, terriers are generally easily trainable using positive reinforcement.
When choosing a toy rat doxie puppy, be sure to visit with the puppy's parents before taking one home. Observing the parents if possible will give a possible owner valuable insight as to the puppy's personality and temperament. Puppies raised by aggressive or timid parents will likely exhibit the same personality traits when older.
