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 Fergusson reflex.
  • Foetus is too small, or not entering cervix.
