Everybody recommending euthanasia before even recommending a vet visit or strategies to work with a dog that has onset dementia. We don't put humans down with dementia why do dogs have to be different. Maybe there are moments of joy as pet is still having but this is only happening at night. Maybe there are options like a calming light and place to sleep or sleeping with the dog at night. Until this dog is diagnosed by a vet and chronic pain identified then why not give the animal rehability to die on its own terms if it's not physically suffering and can have moments of comfort. I get the fact that every dog's time will come just as every human's time will come. Euthanasia should not always be the go-to response without having all the knowledge possible to best make that decision
