Kneecap Was Normal at 4 Months but Slips Now
Thanks so much. I can't seem to get the answers I need. I hope you can help.

Yes, a slipping kneecap can appear later even if it was normal at a puppy check. It's usually a developmental problem that shows up as the bones grow, and some cases aren't evident until later in life. The Orthopedic Foundation for Animals only issues a normal patella rating to dogs 12 months or older and recommends periodic re-exams for this reason. Medial luxation is considered inherited, so it can appear in puppies of parents who never showed signs.
Injury can occasionally cause a kneecap to slip, but in a young small dog with fine bones it's more often developmental. Jumping off furniture doesn't cause the underlying problem but can make it worse, so ramps or steps help. Ask your vet what grade she has and whether both knees are affected, and mention the dragging, since that can also come from a back problem.
