While pugs can certainly sit and walk like other dogs, the conformation of their hind limbs is not solely responsible for these movements. Pugs' ability to sit and walk involves various aspects, including their overall skeletal structure, muscle development, joint flexibility, and coordination.
Pugs' shorter legs and bowed hind legs contribute to their unique appearance and distinctive way of walking, which is often described as a "rolling" or "waddling" gait. This specific gait is a characteristic feature of the pug breed and is not a result of their hind legs bending in a way that allows them to sit or walk like other dogs.
In summary, while pugs can sit and walk like other dogs, the bending of their hind legs is not the primary factor that enables these movements. Their overall physical characteristics and unique gait contribute to their distinctive sitting and walking postures, which are intrinsic to the pug breed.
