Because the dachshund-corgi mix, also known as a dorgi, is not a pure breed, the temperament of an individual dog cannot be predicted. The dog can have any combination of the characteristics of the two parent breeds.
Corgis were originally bred to be cattle drivers and are very active dogs. They can be noisy and may try to herd people by nipping at their heels. Corgis can be wary of strangers and aggressive toward unfamiliar dogs. They are generally easy to train.
Dachshunds were originally bred to hunt small animals. They are very active and can be difficult to train and housebreak. This breed tends to be noisy and aggressive, and it likes to dig, snap and guard.
