I was walking around my neighborhood and a dog jumped on me. i don't think i was bit, and i didn't see any bite marks. it's possible that i was scratched but i didn't see any scratches when i got home. any reason to get rabies pep treatment?

Contact your local health department for guidance. They usually control the local supply of PEP vaccine and are aware of local rabies activity. It does not sound like a worthy exposure, but they will decide if you need to seek an exam and or need the shots,

Rabies transmission is not likely in above described circumstances. A fight or flight reaction combined with health related anxiety appears likely and discussing it with your doc may help in alleviating such symptoms.
