Q:

How long is it before rigor mortis sets in for dogs?

A:

Rigor mortis typically sets in three to six hours after death. However, rigor mortis sets in more quickly in smaller animals than in large, so a very small dog might stiffen within a few hours.

Rigor mortis sets in several hours after death, but the time period varies depending on the size, weight, condition and heat of the dog. Cold animals set into rigor mortis more quickly, while warm animals take longer but also begin to smell sooner. After onset, rigor mortis typically lasts anywhere from eight to twelve hours, but it can last for longer or shorter periods depending on the weather and the animal.

  • Q:

    What causes rigor mortis in animals?

    A:

    According to the Encyclopedia of Death and Dying, two to eight hours after death, the body stops producing adenosine triphosphate and muscles begin to stiffen. This occurs in part because oxygen no longer circulates. Other post-mortem biochemical changes also cause abnormal contraction of the muscles because the body is unable to remove the by-product lactose from the muscles to prevent them from stiffening.
