As most have said "nobody knows your dog better than you". I totally relate. I have a 16 year 2.5 month old basenji named Zak. Zak has CCD (canine cognitive dysfunction = aka doggie alzheimer's). He paces, he circles, he has fallen down and took his time in getting up. He wears a belly band as he will pee anywhere and everywhere. I have no stairs, so that's not a problem. He hasn't had any seizures or at least non that I have seen anyways, because I still work. He does sleep alot. But, he loves to eat. He haslost alot of weight and drinks alot of water. I have him on SeniLife, Animal Essential Heart Health, and Joy Organic CBD oil. I feed him Purina Pro Plan Bright Minds for seniors. It promotes alertness, and mental sharpness. I also belong to a CCD support group on Facebook which members are going through the same thing, or just the start of this journey, and some have had ended their journey. Lots of love and support and things to ask your vet. Zak is totally deaf. I think he can hear some VERY loud noises, but not me talking to him. I am questioning myself as to the quality of life that Zak has. Sometimes he gets off the couch when I get home from work, only because he see's Mr.T (10 year old basenji) get up, and goes to the door. He looks forward to his meals. Doesn't seem to be in pain, but I know his time is coming. I've had him since he was 4 months old, and its hard to see him like this. My 17 year old female had CCD really bad, and one night just before I got home from work, I believe she had a seizure, and T attacked her. I got her cleaned up as best I could, as she hates water with a passion. She didn't want her dinner. So, I put her on her bed, and covered her up. She was ok when I went to bed, but had passed before I got up in the morning. It hurt that I wasn't their to comfort her during her time. She was also deaf, so talking wouldn't have helped, but just giving her some soothing pats and scritches I think could have helped. I don't know. If you are on Facebook, go to the Canine Cognitive Dysfunction group. You will have to join, but oh so worth the help and love and information.............everybody is very supportive as they are all going through the same thing. Only you know your dog the best. Don't let anyone tell you otherwise.......including your vet. Virtual hugs to you, its not easy. But he is family and you treat them like family til their last breath.
