Dog recently vaccinated for distemper, fears for my ferrets.

[Em]

Recently my dog was vaccinated for all of his shots as a starting point, my ferrets have their rabies, but are getting their first distemper in a few weeks. I did not realise that the vaccine they give dogs was modified live and I tried to do extensive amount of research after the fear became apparent for me; both ends of the situation are  telling me different things. What my huge fear is, is that my dog will shed the vaccine version of the virus through his mouth/faeces/urine/nose and give it to my ferrets via "vaccine shedding". I understand shedding is different than transmission and this virus is weaker due to its modification, but because ferrets are so sensitive to CDV, I'd reckon I could equate them in a category of immunosupression or compromised in which case they can still get it very easily. 

I'm keeping them in their cage for the time being as my fear has become big enough to become paranoia. I've called several different veterinarians and they say the risk is relatively low, but it can still happen. It has been a week since my dog's vaccinations and today he came into my room on accident while I was not home (as a family member had noticed), he has a bit of discharge from his eyes and itching, but that is also because he has seasonal allergies. I'm in distress and I really don't know what to do, as I can't get an earlier appointment for their vaccinations. 

Am I being severely paranoid?

Yes, but I don't blame you.
Considering ferrets are also vaccinated with avian sourced modified live vaccines with few reactions, I'd say your ferrets are safe. Keep them separated if you have a slobbery dog that urinates on the floor or walks through its own poop, of course.
