Short-legged dogs can grow, but their size and limb length do not change significantly. The short legs of short-legged dogs are determined by their genetics, which means that their size and limb length usually do not change significantly as they grow. However, they still go through the process of growth and development and require proper care and attention to ensure their healthy growth.

In fact, all dogs will go through the process of growth and development as they age. This includes the development and maturation of various organs such as bones, muscles, and internal organs. Short-legged dogs are no exception and they also go through these growth and development processes. However, due to genetic limitations, their body shape and limb length will not change significantly.
