When in doubt, consult a vet.

I just had my girl in for RI treatment. There is some new type of injection they have that lasts 2 weeks. I paid $100 total, $50 for the appointment, $50 for the shot. This way I don't have to give her shots or oral medicine every day. I'm going to bring her back in in a few weeks for another.

It could be a shed problem. It's up to you; you could bring him in just to be sure, or you could wait until he's out of shed. But if you notice any mucous at all, bring him in immediately. RIs are easy to treat, but can get out of hand very quickly, and can ultimately result in death.
