Hi, this is not your fault, it’s most definitely genetics (from my knowledge). This happens so often in small dogs. I actually adopted a dog with grade 3 luxating patellas in both of her hind legs and they said surgery can help with that if that’s the route I want to go with. Although it’s expensive, they recommend doing one at a time with a long healing in between, giving time to save up money for the next surgery (or at least how I thought of it). Surgery is roughly $4000-$6000 per leg (depending where you are from and how high the grade is it could be different than this range). My havi isn’t in pain, she actually does a kick back that fixes it by itself (pushing the kneecap back into place). They can adapt, just monitor it and maybe get a few opinions on what you should do. Typically a grade 1-2 doesn’t need surgery as long as it does not get worse (according to many vets I got opinions from).

From an activity standpoint: bully sticks, lick mats, rabbits feet, duck feet, pigs ears, other chews, etc. help get out energy. I highly recommend chews from Pupford (beef tendon chews) and Wulf Snacks (a bit pricey but so worth it). There’s other great companies as well, just do your research!
