Back leg - why does she do that?

Hi,
My 4 year old miniature schnauzer is healthy eats great food but once in awhile she won't step down on her back leg
She usually is that way for a day then she is back to normal
I have not taken her to our vet yet.
She won't jump up on the couch when she is that way
What do you think is going on?

Much appreciate your answer
I know you are not seeing her.
But if you think I should bring her to our vet I will
She is not like this very much but just once in awhile
Appreciate what you have to say
Vet says she is in excellent health
Thanks
Beverly
