I bought a puppy from the pet store a few days ago. When we first got her she didn't walk on the grass. Now, she is walking, but she doesn't smell around to pee. Within 5 minutes of being outside she messes in the house. I'm not yelling at her because she doesn't know any better. When outside she usually plays with leaves and chews on the grass. I don't know what to do... she goes out regularly and I stay out there for about 15 minutes.
