* Protracted birth due to weak or absent uterine contractions.
=== Primary Uterine Inertia ===
* Lack of Oxytocin Receptors
* Lack or failure of Oxytocin release
* Lack or failure in Prostaglandin release
* Obesity and lack of excercise in bitches. The small foetus cannot apply enough pressure on the uterine wall and cervix to set up the [[Parturition_-_Endocrine_Control_of_Parturition_- Anatomy & Physiology|Fergusson reflex]].
* Foetus is too small, or not entering cervix.
=== Secondary Uterine Inertia ===
* Dystocia with subsequent muscle failure
* Large number or size of offspring causes the uterine muscle to become stretched and fatigued.
* Common in sow, bitch and guinea pig
