My little Polly is 1 year 4 months old. Lately I've noticed her walking a little "funny" with her left hind leg, kind of stiff like. Also there have been 2 occasions where she was playing where she let out a yelp and started walking really stiff as if she was unable to bend her leg. She hobbled around for a few minutes and after I picked her up and gave her leg a little rub she went back to normal. I've looked it up and it sounds like a patella problem? I am rather surprised though if this is the case, as she is very young, and her parents and grandparents have all been rated "very good" by the orthopedic foundation. She is a very petite cavalier (she was the runt of the litter) at just over 10lbs. Not sure if her small size could contribute to the problem? She did come with a 2 year genetic health guarantee (would this fall into that category??) and also luckily, I health PetPlan insurance on her which should help should she need an operation....heaven forbid. I know our vet checked her over including her legs, how she was walking, etc when she was about 7 months old and didn't see any issues. She has a vet appointment next week but wanted to see what you guys thought? Thanks!
