So here is the update...
Misha is about 80% DEAF, probably caused by a combination of getting so sick with Diabetes and a massive infection. She can hear only loud noises. We do not expect her hearing to return.
Her infection is GONE. Tonight she will take the last anti-biotic pill. But the recent ultra-sound showed a clear bladder with no infection; that is good news because that was causing all sorts of problems.
She is SLOWLY losing control of her rear legs but is in ZERO pain. This is a brain disorder, it happens in any age dog, we are lucky that she is an elderly dog and honestly hope she dies before losing total control of her legs.
The DIABETES is under control and she has to have blood tests every other week, when we adjust her insulin level. She is currently on a fairly low dose, takes 2 shots per day, and that seems to be working well.
On a bad day for her she will fall down for seemingly no reason and has a very difficult time getting back up. On a good day she just has a tough time standing but it is less of a struggle and once she is up she seems to be pretty stable and will walk around her fenced yard, help us with spring clean up chores in the yard, etc.
I have ordered a folding ramp to help get her into/out of our SUV. Amazon says that will be delivered on Monday.
I also ordered a glorified towel (towel with 2 handles on it) that can slip under her torso to help lift her. It is for use when she is not wearing a collar/harness combo that has 2 handles to help lift her.
The collar/harness combo is not yet on order, and is not designed to be used 24/7. So while it appears to be a great solution, it has to be periodically removed. >>>

Overall she seems happy. She will bark if she wants to come in, will walk to the door to be let out. She loves to come into the living room to watch TV with us . . . which includes going outside through the front door, around the house and down a small slope then inside through the living room patio doors. She cant make it down the 6 stairs that it takes to come down into our living room so the outside route is the only option. She has NO CLUE that her back legs are not working well and there is apparently NO PAIN involved in that issue. As for the DEAFNESS it causes her to be surprised sometimes as we wake her up by petting her, or sometimes when she is awake she doesn't realize we walked up near her and gets a bit of a 'shock' when she realizes there is someone next to her. She is clearly feeling and acting like a normal older dog (she is 11.5 in a breed that lives about 12 years) and shows love and affection and gets the same.
Not sure how much all this has cost us so far, but its in the many thousands. And we would do it all again.
