Here's a general idea of their growth timeline:
* Puppies: Dachshunds grow rapidly during their first year. They typically double their birth weight within the first 4-6 weeks.
* Year 1: Growth slows down after the first year, but they continue to fill out and develop muscle mass.
* Year 2: By the end of their second year, most dachshunds have reached their full adult size.
Important note: It's important to remember that every dog is an individual, and some may grow faster or slower than others. It's best to consult with your veterinarian for personalized advice on your dachshund's growth.
