My dog for the last few days has been licking her vulva & today I noticed one side is noticeably swollen & feels like there is a small-size hard lump.

The vulva looks swollen indeed. Stevie may have vaginitis, which is not uncommon in young dogs. It is usually mild but irritating bacterial infection of vulva. The other explanation I can think of is a small wound or insect bite the triggered the itchiness and irritation and Stevie by continues licking the area, made it worse. First of all, you need to stop her from licking the vulva. Head cone would be ideal. If she doesn't tolerate a cone you could try a diaper, but a cone would be better. If the swelling does not go down or at least improve in the next 24hrs you will need to take Stevie to your local vets for a check up.
