My dad is 92, has dementia but lives at home with a daytime caregiver. He has a dog, 12 yrs old, blind, deaf and is diabetic. He requires 2 shots a day which we pay someone to cover over and administer the shots. The dog wears a dog diaper and also is now constipated. I know, I know, the dog should be put down but it is my dad's joy and reason for living. All he does is love on him. Dad's at the point where he doesn't care if the house smells or he smells. He sobs and sobs (actually wails) when the dog is gone for a couple of hours when he's at the vet. I'm afraid dad will go downhill when the dog is gone but I don't want the dog to suffer anymore. Will dad ask everyday where the dog is and then cry all over again. Its just so awful and sad.
