New puppy going outside

Question
I just picked up my chocolate lab Saturday and he is 7 weeks old. So far he has been de-wormed twice and had the spectra 5 shot on December 30th. Is it ok for me to start bringing him outside in my fenced in backyard to potty train him. Currently we r using the wee pads inside out kitchen.  

Answer
Yes.  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.  See http://www.apdt.com/po/news/docs/Messer_Nov06.pdf
