Here is my LP story and I have no doubt it is Genetic.
Roxy and TJ (same father - different mothers)
Roxy was 9 months when I started to hear the click in both her legs. Vet confirmed LP. I saw 2 Ortho Specialist who confirmed LP. Roxy had surgery. He rear legs had a slight curvature to the bone structure. Both grooves were very shallow. One knee cap was facing the wrong way.
TJ has LP too - Thankfully he shows no signs of pain or discomfort.
My groomer has 2 girls (same parents as Roxy) - Both girls have LP
I have come in contact with another person that has a girl from the same breeder (same father as all the above - different mother) - and yes the pup had LP too
**********
So we have 5 pups ALL have LP in both legs
(Same father for all 5 pups - 3 different mothers)
What I have learned about LP is this. In most cases, they can not say LP is genetic for sure, bc most cases the pup isn't actually born with the patella luxating at that moment. BUT the genetic makeup (bone structure, groove, etc.) is all set up for the patella (at some point) to start to luxate. Get it
I honestly think it is a sucky thing that a lot of breeders just get a free pass for
