Ok, so hubby took her to the vet. Vet spent a good amount of time with her and not any patella issues or anything they can feel/see. They went for a walk outside, and of course she barely hobbled!
At this stage, thinking a sprain, and to keep her on short walks/no jumping.
As she is staying at the kennels later this week for a few days, the vets are going to check on her again. (vets and kennels are joined together)
