Rigor Mortis, a stiffening of the muscles, usually starts to take place at around 3 hours after someone is dead with full rigor occurring at about 12 hours after death.After the 12 hour mark the rigor slowly ceases and at around 72 hours rigor disappears.ow long it takes rigor mortis to set in depends on the size of the  dog. The stiffening of the muscles usually begins within three  hours of death and will affect small dog â¦ s much more quickly than  large dogs.
At the moment of death, the muscles relax completelyâa condition called primary flaccidity.. The muscles then stiffen, perhaps due to coagulation of muscle proteins or a shift in the muscle's energy containers (ATP-ADP), into a condition known as rigor mortis. All of the body's muscles are affected. Rigor mortis begins within two to six hours of death, starting with the eyelids, neck, and jaw. This sequence may be due to the difference in lactic acid levels among different muscles, which corresponds to the difference in glycogen levels and to the different types of muscle fibers.
