While this is an uncomfortable subject to cover, it is worth doing based upon how it can have a massive impact on your dog’s well-being. Whether the death is of another dog or a member of your family; grieving is something that they share with humans, and just like humans dogs can react in a irrational way. Often times dogs will become listless, unmotivated or anxious, and you need to be prepared to help them.
The best way to get dogs going again following a death is to make sure that they get back to their regular routine. Generally speaking, dogs are able to bounce back from loss far more than people, but routines like walking and feeding schedules are very important for their sense of security and well being.
Another thing to note, is that some dogs who have become faithful companions to a person who has suddenly passed away, may have to be euthanased due to their age, and how fast their health will decline with the loss of their owners; it’s not a nice thing to do but sometimes it’s necessary. Though you can always try to help your dog instead by comforting them in the way their owner did, even if their owner and their effect can’t be replaced.
