Dachshunds are usually good with children in their own family, but care should be taken as some may snap at children other than family members. Dachshunds normally get along well with other pets, but they must be socialized at an early age in order to live with cats. They can become jealous and irritable, and quick to bite when threatened. Many dachshunds are reserved around strangers, and some tend to bark excessively at passersby.
