Jackson's ears stood up around 4 1/2 months old. He went to the groomer and she shaved the tips of them and up they went! Lol. I was almost hoping they'd stay floppy, but I love them up too of course.
First pic is 9 weeks old.
Second pic is after groomer at 4 1/2 months old.
Third pic is when they stood up by themselves!
And fourth pics is now at 2yrs old.
