@Kembe I have been down this road. My girl Jenna was 17 when she crossed the bridge 2 years ago. She was never fully diagnosed with CCD, but she had all the symptoms. She would pee and poo anywhere, and everywhere. She did use the dog door to the garage. She had gotten stuck behind my washer at one point. I could never figure out how or why she did that. She had to go past them to go outside to the backyard; but some where she hung a right and ended up behind the washer. I had found a box that fit between the washer and the wall, so she never had that problem again. One night she had a seizure just before I got home from work. At that time, I had 2 basenji boys, and I believe one of them attacked her because he did not know what what going on. I came home to find her on the floor in the middle of the room and not able to get up. There was some blood, but could not find any real wounds from the so called attack. I got her cleaned up as best as I could. She could not stand on her own without me bracing her. I laid her down on her bed, and got her food bowl for her since she hadn't eaten since breakfast but she didn't want it. I put a blanket over her. She was resting and doing ok before I went to bed. I was going to call the make the decision to have her put to sleep, but she chose to go on her own terms and was gone by morning when I got up. I felt so bad, that I was not right there beside her. NOW, my 16 year old Zak is pacing, gets stuck in and behind things. He's not been officially diagnosed either. I have him on Senilife, Joy CBD for dogs, and he get Heart Health (Amazon). He still looks forward to eating. Doesn't like to walk that far anymore. We have a meet up for Basenji's on the last Sunday of every month down at Point Isabel (across from San Francisco, CA). He can't walk like he used to for that, so I bought him a stroller. He tolerates it, but still wants to get out and walk some. But his walk is like a turtle at best, and is too slow, so I put him in the stroller until we get over to where we usually stop and gab some and all the while, the b's are running. Since Zak is deaf, I do have to keep an eye on him as he does and will wonder off, and not know where he is. He also has peeing accidents in the house, so he has a belly band for that, I can change and wash them. He has lost weight, went from a large belly band down to a med, and I thought it was really going to be too small for him, but its not and it doesn't fall or come off. He also got stuck behind my dryer very early Saturday morning, it woke me up, him screaming and howling all at the same time. I got that side blocked off now too. I don't know what type of natural medication you bought. Senilife does help and takes time. Am not 100% sure if that or the CBD oil are working. He also gets some mobility chews. I mix the Senilife and CBD oil in with his food in the moring, and the heart health in his evening meal. He will eat, and walk over to check out Mr.T (basenji) bowls or see if there is any food in the cats bowls. He will go back to his bowl and eat some more and do the walk about to other bowls again. I have to watch Mr.T as he will eat Zak's food if I am not in the room or paying attention. He drinks alot of water, so the water bowl has to be constantly filled.
You may want to block off rooms or under tables as best as you can, so she doesn't get stuck too badly. Its the pitts watching your pup get old and forget things and places. Jenna was my first dog that I ever experienced this with. I've had plenty of dogs, but most were gone by the age of 14 and never had dementia. Now, I'm dealing with it with another dog. I am just hoping that Mr.T will be ok. Jenna came from a reputable breeder, Zak was a rescue from a backyard breeder. Mr.T is from a reputable breeder in Arizona, but he was re homed to me from his original owners after they got transferred to Brazil for their job and couldn't take him,,,,,,,,,,,,,,,,he's got his own set of problems............Valley Fever.
I may have not been of much help, but I have been down this road, and am traveling it again. If you are on Facebook there is a Canine Cognitive Dysfunction group that you can ask to join. Lots of really good help and different ideas on medications to ask your vet about.
Don't hesitate to ask questions. We're all here to help as best as we can, but the best place is to talk to your vet. Some vet's are not very knowledgeable about CCD, and if your vet will not give out meds, find a NEW VET.....ASAP. Wishing you all the best for you and your pup.
