Do you have oscar on a leash when you go out? How old is he?
My suggestion is to put Oscar on a leash when you go outside. Walk to the place you want him to go, say "go potty", and then stand there and wait. Since he's on a leash he doesn't have the ability to go far and do his thing in the yard. Instead he has a 5 foot radius around you to pee and poop and that's it. You may have to wait for a long time but eventually he will go. Then praise and treat him. Then either he can have free time, or you can take him back inside. Worked like a charm for morgan.
