* Large offspring may pccur naturally, but is more common with [[Artificial Insemination - Anatomy & Physiology|Artificial Insemination]] with the semen of a large breed into a small dam.
* Passage of the foetus through the birth canal is restricted. The oversized foetus presents three barriers to delivery:
** Head
** Shoulders
** Hips

=== Treatment ===

* Traction can be applied to assist delivery, but this carries the risk of pelvic fracture.
* Caesarian

=== Large Offspring Syndrome ===

* Only seems to arise with [[In Vitro Fertilization - Anatomy & Physiology|IVF]] treatment
* Foetus and internal organs are enlarged
* Musculoskeletal abnormalities
* Increased post-partum abnormalities and mortality
