It can be argued that any dog breed can be trained to be aggressive, and any dog breed can be trained to be passive. The fact is, particular dog breeds are often linked with particular traits. The pit bull is often viewed as an aggressive breed, and the golden retriever is often viewed as a passive, friendly breed. These views, however, are undue generalizations. Aggressive dogs come in many breeds and sizes. As it turns out, some of the most aggressive dog breeds are also the smallest breeds.
The dachshunds have a strong instinct to dig. Their name literally translates to “badger dog” in German. Dachshunds were bred to chase badgers out of holes, therefore, they are high-energy dogs. When dachshunds are unable to relieve their energy in a healthy manner, they can become irritable, obstinate and quick to bite.
