I just had my female lab spayed in September. She was about 16 months at the time and had been through one heat cycle. Fortunately I timed her surgery with my antelope hunt so she didn't have much choice but to hang out until I got back.
The doc said it would take about 2 weeks tops from the date of surgery until the stitches came out. On the second day she started licking and so we had to get the 'elizabethan collar' for her. Talk about ridiculous.

By day 3 she was running and jumping, getting her toys for me to throw, etc. It was all we could do to keep her from ripping her stiches out. Finally my wife decided enough was enough and took her to the vet 4 days early. The vet looked at her and said she was good to go and pulled the stitches. His comment was that the younger dogs tend to heal faster so it was not a big deal.
We spent the next week getting back into the grove and since it has been like it never happened.
