===Bones===
The pelvic girdle is formed by two hip bones which are joined ventrally at the cartilagenous '''pelvic symphysis''' and articulate dorsally with the sacrum. The three components of each hip bone are the [[Ilium - Anatomy and Physiology|Ilium]], [[Pubis - Anatomy & Physiology|pubis]] and [[Ischium - Anatomy & Physiology|ischium]].
The pelvic girdle is formed by two hip bones which are joined ventrally at the cartilagenous '''pelvic symphysis''' and articulate dorsally with the sacrum. The three components of each hip bone are the [[Hindlimb - Anatomy & Physiology#Ilium |Ilium]], [[Hindlimb - Anatomy & Physiology#Pubis|pubis]] and [[Hindlimb - Anatomy & Physiology#Ischium|ischium]].
The bone that articulates with the hip bones to form the hip joint is the [[Femur - Anatomy & Physiology|Femur]].
The bone that articulates with the hip bones to form the hip joint is the [[Hindlimb - Anatomy & Physiology#Femur|Femur]].

The muscles affecting the pelvic girdle and hip can be divided into two distinct groups:
The muscles affecting the pelvic girdle and hip can be divided into two distinct groups:
* '''[[Girdle Musculature - Anatomy & Physiology|Girdle Musculature]]'''
* '''[[Hindlimb - Anatomy & Physiology#Girdle Musculature|Girdle Musculature]]'''
** '''Psoas minor''' - the muscle is marked by many tendinous intersections
** '''Psoas minor''' - the muscle is marked by many tendinous intersections
** '''Iliac muscle''' - a fleshy muscle that is cross-sectionally flat cranially and round caudally. It originates from two heads; a strong lateral head from the wing of the ilium and a small medial one from the ileal shaft. They enclose the '''greater psoas''' and will unite to form a common tendon for insertion.

The bones immediately distal to the [[Femur - Anatomy & Physiology|femur]] are the [[Hindlimb - Anatomy & Physiology#Tibia|tibia]], [[Fibula - Anatomy & Physiology|fibula]], [[Patella - Anatomy & Physiology|patella]] and some minor sesamoid bones. Some of these are involved in the stifle joint, weight-bearing and providing attachment for muscles.

Distal to these bones are the complex series of bones that make up the tarsus, these are the [[Tarsal bones - Anatomy & Physiology|tarsal bones]] and [[Metatarsals - Anatomy & Physiology|metatarsals]].
