Potty training!!! 🐶

Shea
My fiancé got me a puppy two months ago, and he still poops/pees all over the house. Any advice on training him? He's a smart dog. He's a rottweiler/boxer mix although he looks like he could be a rottweiler/german shepherd mix. Oh, and we don't have a crate/cage but we do have a fenced in backyard. I need advice ASAP.
