How can I help my Mother get over the loss of her beloved pet?

That is a terrible way to lose a pet. Death is hard enough, but to not know what happened to the dog has to be terrible.

As suggested, depending on her mental capacity, the idea of saying that a family with children has the dog now and that the children love the dog may help. All of the ideas are good ones. Just understanding her grief and validating it is vital. Much of the rest depends on her mental and physical health.

Please update us. This is something everyone can learn from.

Can you tell us a bit more? Does your mom live alone? Or with you? How far along the alzheimers journey is she?

My mom actually killed her dog by overfeeding him--though I was actively begging her not to. But she could not remember. However, about two weeks after his death, she didn't even remember having him!!!!!

Dogs are wonderful for elders. But elders are not always wonderful for dogs. I would be very wary of getting her another one if she would have to care for it on her own.

GardenArtist gave some really great advice options. I think all of them are worth trying. Depending on your mother, the last one might help change her heart. But if she is able, maybe going to shelters and having time to spend with a dog will lift her spirits and be a distraction from mourning. Or getting a stuffed animal that looks like the dog might help console her. Also, do you have any pictures of her and the dog? Do you think getting one nicely framed would help?

Grieving isn't about getting over and forgetting, it's about coming to terms and feeling better and living with the grief in a way that it doesn't interfere with your life. Your poor mother :( losing a pet is so devastating, especially in her condition.
I hope she finds some peace.

This is a tough situation. You could get another dog, but sometimes it causes someone to mourn the missing dog even more.

What you might try is to locate pet service organizations and see what facilities they go to, then take your mother there to interact with a service dog that's been trained for older people. If she enjoys it and it makes her feel better, you could consider getting another dog.

In the meantime, have you contacted a pet finders group? Put up notices in local stores, papers? Contacted local rescue groups and shelters? Perhaps someone has found the dog and is searching for his home.

Something that can also work, depending on her cognitive level, is to get a stuffed toy dog. Even though it can't interact, just petting the soft fur can be calming.

Another option is to tell her is what another poster calls a therapeutic fib...that you contacted shelters and someone found the dog and brought it home for their young child, who just adores the dog, and the child would be very upset if the dog were taken away. Then segue into whether she'd like another dog of her own.
