When is a dachshund an adult?

Dachshunds are considered adults at around 12-18 months old. While they reach their full size earlier, their bones and muscles continue to develop during this period.

Here's a breakdown:

* 6-9 months: They are still puppies, but are much more mature than younger pups.

* 12-18 months: They are considered fully grown adults.

* 2-3 years: They reach their peak physical condition.

Keep in mind that this is just a general guideline. Individual dogs may mature at slightly different paces depending on factors like breed, diet, and overall health.
