I got a 3 month old puppy yesterday, he's a Dachshund. He's gone to the bathroom outside like once and i praised him a lot so he gets the idea. But he like won't go outside or something. We have a really big front and back yard so I was out there with him for at least an hour walking around and stuff and i kept stopping and waiting for him to go, and he didn't. We went back inside and a couple minutes later he peed on the floor. He did that twice, he won't go when i take him out.

Whats the best way to potty train him? I tried putting him outside by himself and watching him from outside but he just stood at the door staring at me....help?
