re: Am I expecting too much from my lab puppy?

Stop using treats so much and start forcing him to listen. Only say the command once and if he does not obey then make him sit, come, etc. If you say it multiple times then he thinks he doesn’t have to listen to the first few.

Also, I’d look into running that much with a puppy.. I don’t think you’re supposed to run them like that when they’re still growing and developing especially if it’s on concrete.
