Yes, long haired dachshunds are good family dogs. They are very loving and loyal to their owners.
While they are dedicated to their owners, dachshunds can be aggressive and should be socialized from a young age so that they will do well around children and other pets. With proper training, long haired dachshunds can interact well with children and pets, but they should still be supervised.
Dachshunds can be very vocal and have a deep bark that can be an issue for families with babies or people living in apartments.
