As i say, i suspect she'll always be a 99%-er.
this changed enormously
it had come to the point that I could safely take her on off leash walks around the neighbourhood (I waited til it was dark and no danger of small humans to be distracted by). I'd carry the leash and she'd sashay along smartly - sitting at corners without being asked/prompted.
From life in a crate to walking off-leash. She came a long way - and still sounded like a bubble machine when she snored.
