Good job and keep reinforcing this, Heather. Hopefully you'll get her beyond this fear. She looks like she's just big enough that she between the small dog size that bunny hops up each step like mine do and that of a larger dog that uses one foot per step and has more of a climbing, stepping motion.
I have 2 that are very afraid and that's after working with them. When Dixie was younger than Tricky, she went through the back of a set of contractor steps (no backing on the riser) when just learning steps and did a somersault landing hard on her back, belly up, laid there stunned. Ever since then she's always tried for 2 at a time and then would sometimes face plant into the kitchen door because she couldn't get stopped in time. Now we've tacked down a rug and also have a ramp in the garage for the dogs. Cinnabon's knees are bad enough and legs just weak enough that went she does try to come up, she always bangs her knees which then reminds her not to try again for a while. She's lifted up each time.
