My dogs spay incision has pimple like bumps on it, the incision is healed up She is 10 months old. She doesn't seem to be bothered by them,

The small bumps are probably the suture underneath the skin. The skin reacts to the suture forming these small bumps. They never appear to be painful to the dog... This should go away in a few weeks.

Of course, any type of concern, especially after a surgery, should be checked by your vet.
