Hey Radio - maybe there are other things your Mom can try - like medications for the dog. I too have an older dog and she takes arthritis medicine (Previcox) for her hips and a medication (Anipryl) for her doggie dementia (that is probably why your Mom's dog is is barking and whining - it is a symptom of doggie dementia - canine cognitive dysfunction). Yes my older dog is a bit more work but I would find living with someone with a "hot" tamper even more work. I take care of my older dog as I would take care of an older beloved relative - it is a labor of love and is merely a repayment of all the years of unconditional love she has given to me. All in all, you might gently encourage your Mom to at least talk to the vet to see if there are medications that can help with the dog.
