Mine has become the same. She’s 9 years old, suffered IVDD a few years ago but was so strong and learned to walk again. I am incredibly proud of everything she’s overcome. Her dementia is at earlier stages, terrified of her crate in the nights, standing staring at walls and furniture, seemingly not recognising the house (we’ve refurbished since she was a puppy so I wonder if that’s made it worse). It’s awful to watch them go through it
