What am I doing wrong with my puppy potty training?

you're doing fine! unfortunately...it will take at least the first 6/7 months of a puppies life to get potty trained- just keep taking him out whenever eat eats/plays or after he wakes up from a nap. I know a friend who attached a jingly bell to her door, and started making the puppy hit it before she took it out for a pee, her dog then soon learned when he jingled the bell on his own- it was pee time. Patience is key! Sorry...but puppy training is not a quick thing, it takes time.
