It's possible, I suppose, that her hormones are still out of whack. Was she in heat, or close to it, when she was spayed? It takes about 6 weeks post-surgery for the hormones to settle down.
I've heard that bitches can have a temporary increase in testosterone right after spaying, which if true, could explain her extra energy and "naughtiness".
How old is she now?
She is 16 months. She just ended her heat. The vet commented that her uterus was fairly large.
Her behavior is the same one that I had experienced maybe 7 months old?
