Personally I agree about having carpeting. I understand completely.
Now that being said....how often do you take him out? He is small....smaller means a smaller bladder and he'll need to go more often. I took mine out hourly...on a leash, repeated the go potty phrase...and stayed usually until someone went potty. I took them out immediately in the morning when they woke up and then hourly. I did not wait for signs...we just went. We also used the same door each and every time....with the hopes eventually they would know what going to that door meant.
With poops I think you just have to pay attention when he's going. Mine will both go first thing in the AM....and don't go again until we get home from work at 5. This has no bearing on when they've eaten. Sometimes they'll eat breakfast at home...and sometimes they wait until we're at work to eat.
To be honest I really think it was close to a year...before they really got it.
Another thing....Reese gets distracted....we'll let them out to potty. Ramsey will go immediately...then asks to come back in...Reese follows. Do a "pee pee" check on Reeser...nope not wet...but him back out.... you go potty Reese.
