How long does it take for a long haired dachshunds coat to come in?

The coat of a long-haired Dachshund typically begins to develop fully by around 12 to 18 months of age. Initially, puppies may have a softer, shorter coat, which gradually grows longer and denser as they mature. Factors such as genetics, diet, and overall health can influence the rate of coat development. Regular grooming can also help promote a healthy coat during this time.
