It is very likely she has a condition called patellar luxation. This is where the ligament in the knee goes in an out of the socket. She can have this surgically repaired if it becomes a chronic issue and impedes on her quality of life. Otherwise joint supplements (i.e. Dasuquin) may be able to help reduce some inflammation and pain in the joint itself. Have your vet do a simple physical exam and check the knees. Patellar luxation is detectable by a physical exam and doesn't require radiographs to diagnose. I wish you well at the vet. Best wishes with Mindy and take care.

Poor Peanut! Given that she is a toy breed dog, she could be suffering from a condition called a luxating patella. This is when the kneecap moves out of it's correct anatomical position, and it would cause her pain, leading her to limp. The limping could also be caused by a spine, hip, or joint issue. I would recommend taking Peanut into the vet first thing in the morning. The vet can do a physical exam, lameness exam, and possibly x-rays to diagnose what is causing her limping, and can prescribe a treatment for it.
