You may notice that your dog has a different or stronger odor than usual near the end of life.
Most researchers believe dogs can remember important people and events for years, possibly until death. A 2021 study in the Journal of Veterinary Science found that dogs often show grief-like behaviors, such as reduced appetite and increased lethargy, after the loss of their primary caregiver.
