Hello, new here but the picture of your Hobo reminded me of another 14 yr.old dog that I know. You don't say how old Hobo is but if he is eating well, drinking , not in any pain and is content to be by your side then maybe his time isn't here yet. The 14 yr old I'm thinking of has had a stroke, is deaf, mostly blind and also has canine dementia. She needs a ramp to go up and down short stairs but she never has accidents, loves a few very short daily walks, loves to swim and passed the vet check with flying colours. I would say to go with the flow - your dog willet you know.
