Lately I am getting compliments on Deja's healthy and lean looks, especially since most people think she is a year old while she is 6+ years old. I am not writing this to brag but I am wondering what causes this. She gets raw from scratch in the evening and a handful of kibble in the morning to settle her stomach and to add extra nutrients. She gets plenty of exercise and is intact. The latter is my main reason for writing this. Will a full spay change her sleek coat, her drive etc? I am not interested in partial spay as the uterine stump can still get infected. I am planning on spaying her to prevent pyo, now she is getting older. Thoughts?
