What is Rigor Mortis?
Rigor mortis is a natural postmortem process that happens in all mammals, including dogs. It is the stiffening of the body due to chemical changes in the muscles after death. This process is a clear indicator that death has occurred and is often used by veterinarians and pet owners to confirm a pet’s death.

The Stages of Rigor Mortis in Dogs
The process of rigor mortis in dogs goes through several stages.
1. Immediate Death Stage
Immediately after death, the dog’s body is still flexible. This is because the muscles still have residual oxygen, allowing them to relax.
2. Rigor Mortis Onset Stage
Approximately 1 to 2 hours after death, the body begins to stiffen. This is the onset of rigor mortis. The process generally starts with the smaller muscles, such as those in the face and jaw, before moving to the larger body muscles.
3. Full Rigor Mortis Stage
The body reaches full rigor mortis around 6 to 12 hours after death. At this stage, the body is completely stiff.
4. Resolution Stage
After about 18 to 36 hours, the body begins to relax again as rigor mortis subsides. It’s worth noting that, on average, rigor mortis lasts about 3 to 4 hours in dogs. However, the time frame can vary depending on various factors.

Factors Affecting the Duration of Rigor Mortis
The duration of rigor mortis in dogs is influenced by several factors:
- Size of the Dog: Larger dogs tend to experience a longer period of rigor mortis compared to smaller dogs.
- Environmental Temperature: Cold environments can prolong the rigor mortis phase, while warmer environments can shorten it.
- Cause of Death: If the dog died due to a disease or condition that affected its muscle mass or overall health, it could impact the duration of rigor mortis.
