Puppy in a classroom

Question
Hi. I live alone and just got an 8 week old yorkie puppy.  I teach at an elementary school and am unable to stay home during the day.  My puppy has had her first parvo, distemper, and heartworm shot but has not completed all vaccinations.  I was planning on bringing my pup into the classroom while I am teaching.  I have purchased a play pen for her so that she is out of contact from my students. Will my puppy be safe if she is in the classroom but out of human contact (besides me?)  Is this a horrible idea? Any other suggestions? Thank you.

Answer
As long as the school officials allow it, I see no problem.  I have taken puppies with me while teaching in a community college with no problem.  The one thing I would watch is what she might find to eat.  the children's food, raisins and grapes can be quite toxic as well as sugarless gums.  Art supplies may be bad too.  

It is a little different but I know some people that raised a puppy for a service dog school and kept it in their class room.  It worked fine.  

What you need to do is avoid dogs of unknown health.  The period between 6-12 weeks is a dangerous time.  One sniff where a sick dog relieved itself in the last 6 months can bring on parvo or another life threatening disease.  Fail to expose it to strangers, including men, women, children, noise, etc. and you could end up with a misfit you can't take out in public.  They also need continuing contact with other dogs, but it must be limited to ones you know are getting good care.

If the school officials object, you may need to find a neighbor or professional dog walker to give the puppy a mid day break if you can't take it to school.
