I was relived when I discussed it with my mom that the puppy had an owner (wasn't a stray!) and it was healthy. (I have seen the puppy again like 5 days later, probably)

But while I was looking at my knee, I noticed 2 spots that looked redder than others. They were faint and I didn't notice them until 8-9 days after the "exposure". Can these spots be related to a dog/puppy/canine bite? I also have a sensation on my left knee, aka the leg where the exposure did happen. (It wasn't right on to my knee though, the puppy was BELOW my knee!) I'm still worried that the puppy may have extended its head to lightly bite me but I didn't feel anything like a bite (even if not painful) or mouthing me?

Maybe I get the sensation due to my anxiety that returns back? It also doesn't happen just at the suspicious spot. 

Let me explain the spot: There were two dots that were blurry red and I have only noticed them 8 days after the first time I got anxious. (I have never seen any bleeding or scabs, I'm completely sure!) I have also scratched my knee for a while (not from the puppy) so it may be the result of the scratches because my toenails were too long and my brother was overly active? It has never bled, and there weren't any bruise as well. (I was wearing a clothing but even then it wouldn't be a thing) I don't have a picture with me right now but I'll post the pic if I get the chance.

Could that be a puppy bite that needs attention?
