stiff shoulder

Question
hello, what does "a horse has stiff shoulder" mean? my friend told me that kathiawari horses stiff their shoulders.

Answer
I am not sure exactly what your friend means.

Horses can be stiff in their shoulders for a variety of reasons.....physical injury,
arthritis, poor saddle fit, etc.

A breed can have the tendency to have a STRAIGHT shoulder, which could lead to some of these problems, but not in general a breed to have a "stiff shoulder."
