The Dachshund's juvenile period spans roughly from three months to about twelve months of age, though some individuals continue filling out well into their second year. During this time, the puppy's elongated body takes on its characteristic proportions, with the chest deepening and the legs remaining short and sturdy. Standard Dachshunds will undergo a more extended growth phase than miniatures, which often approach their adult size by eight to ten months.
Weight gain should be steady but controlled. An overweight juvenile Dachshund places excessive strain on a spine that is already predisposed to intervertebral disc disease. Regular weigh-ins help you adjust food portions as the puppy grows, and your veterinarian can confirm whether the rate of growth is on track for the variety — standard, miniature, or somewhere in between if the parentage is mixed.
The coat also matures during this stage. Smooth-coated Dachshunds will develop their sleek, glossy finish, while longhaired varieties see their feathering fill in along the ears, chest, and tail. Wirehaired juveniles begin developing the distinctive rough outer coat and softer undercoat that define the variety. Understanding which coat type your Dachshund carries helps you establish grooming routines early.
Bone growth plates in the legs remain open during this period, which has direct implications for exercise intensity. High-impact activities such as jumping from furniture or running on hard surfaces for extended periods should be limited. The Dachshund's short stature already concentrates force on the joints, and protecting developing bones now pays dividends in mobility later.
