CM stood up at 5 or 6 weeks no problem but Jasmine have been up and down, when they are teething can can do that, I would shave them down 1/3 off the ear and then bend them like a taco and tape them up for 4 to 5 days, thats what I had to do with Jazzie's, but now they are up, but leave them up for aleast 4 to 5 days, and if they start going down do it again
