Thanks for all the replies and support. I am feeling better about my decision to just wait and see. I've been reading a lot of personal stories and seeing people freak out and do surgery right away that it made me feel like I wasn't doing enough. Mia's my little girl and I just want the best for her.
Her knees are odd. She definitely never limps or is lame. She is very agile and active. But by all counts since her knees are graded higher she should be limping some right? My vet had said he had seen some dogs that have knees riding out 24/7 that are fine. Mia's right knee is graded worse but sometimes it does seem like she barely favors her right knee. It is something you'd have to really be looking to see though.
