Cali has been diagnosed with grade 4 lp in bith knees. They donot bother her at all so far and she is going to be 3. The vet said she may never need surgery or she may so we are taking a wait and see approach. One of the things that can help is keeping them from getting over weight. Cali is a tad overweight but I am working on that. Of all of my girls, Cali is the one who loves to go on walks and the other like to be in the stroller but not her. So I figure if her knee's start bothering her I will put her in the stroller. Good luck with your baby |
