At my MIL last doctors appt., her doctor told her that she's going to need to start getting use to living without the dog. She is a flat out 'no' on that one. If I've gotten the right info on Alz stages (1-7), my MIL is at a early to mid 5. At the doctor's advice we did get her to quit smoking, but how do we know when the dog should go. If he's now saying she needs to start doing this... should we just put the old dog down now and do it quick like a taking off a band-aid?
