My advice will be to keep the pee pee pad available for him outside the playpen also. Also, keep a hawk-eye on his every movements, this is a-must so you can learn his go signal. My puppy has a go signal. When he wants to pee, he will smell everything around him before he squats in which time you should said no and pick him up immediately unto a nearby pee pee pad. Continue to do this until he gets it. He won't get it immediately so be patient and be consistent.
Restricted his movement to the place that you will be able to supervise him continuously. Put more pee pee pad than necessary inside and outside the playpen until he gets it in which time you can reduce the amount of pee pee pad in the places that you want.
For example, Charlie (my toypoomixterrier) now is 10 months old. When he was 8 weeks old, he literally didn't leave his playpen unless we're home and playing with him. We kept 2 wee wee pads inside his playpen which attached to his crate. If we play with him, we'll restricted the playing area around the living room and we have four or six wee wee pad, two on each side of the sofa, one in the kitchen, one near the door and two near the outside of his playpen. At night, we moved his crate into our room and place four wee wee pads surrounding his crate. He often pees around 2 am then he'll pee again at 6 am. At 6 months old, he finally gets it so we reduce the amount the wee wee pad to only two wee wee pads. One near the front door and one inside the bedroom. Also, we use a tray to help him not miss the wee wee pad.
Be consistent with your poodle to help him succeed in this stage. There's a lot more for him and you to learn. Also, please purchase a Zero to eliminate the odor when he accidentally pees on the floor. This is very effective in removing your puppy's pee scent so he won't repeat his accident there anymore.
I would suggest wee wee pad brand and don't buy the cheap petco brand cause they don't attract the puppy enough instead giving mixing signal. I get mine from Amazon, they are having good deals sometimes and will email you the good deal when you sign up with them.
Best of luck and let us know if anything else is bothering you.
