He reached two pounds, so I was able to give it to him
I just waited it out...he's never (well, very, very rarely at this point) outside. Since he still doesn't have all of his vaccines, I rarely take him out. He goes potty on a pad, and plays with us for his exercise right now, mostly. I figured it was better to wait and be cautious. He's covered now though.
Thanks for all the replies.
