Here are some additional factors to consider:
* Size: Standard dachshunds are typically larger than miniature dachshunds, so they may take a bit longer to reach their full size.
* Gender: Male dachshunds tend to be slightly larger than females.
* Diet: A healthy diet can help your dachshund grow and develop properly.
* Health: If your dachshund has any health problems, it may affect their growth.
If you are concerned about your dachshund's growth, it is always best to consult with a veterinarian. They can assess your dog's individual needs and provide guidance on how to ensure they are growing properly.
