Is something wrong???

I just got a new puppy about 4 days ago. He's a chow mix. We have just started to potty train him, and he's had a couple accidents which was expected. But the problem is, the only time he's gone potty was when we kept him in the house he peed twice and only did number 2 in the house once. But after we decided to leave him outside until he went potty, he hasn't gone potty at all as far as I know. I've been watching him very closely to see if he uses the restroom outside, and I haven't seen him go potty yet, and it has been two days! Is something wrong????
