We potty trained him to go on puppy pads...Of course at first he didn't know where to go, but when he peed off the pad, we dabbed a little of the pee up with the pad, so that his scent would be on it. Then, we put that pad down in its place.
If that makes any sense to you guys...I can clarify if need be. hehe
Also, the first day, we let him show us where he wanted to pee, meaning that if he picked a spot where he liked to pee, we would put a pad down there. That way, he always peed on his pad, and we would tell him "good boy" and throw a "PARTY"! He loved how excited we got over that and responded very well. Positive reinforcement is definitely the way to go, hehe

Then slowly, we started taking away pads, and putting them where we wanted him to go, moving them over just a little each time until we got them in the right spots.
He was completely trained within 2 months

Sorry about the long post, I just wanted to be as detailed as possible
