Going to go back to the old food for now. I hope he isn't feeling too bad :( We were just trying to get him the healthiest food, but I think his previous food is just fine too.
Thanks everyone for your support.
I doubt it's the food (unless it's making him feel sick for some reason).
To me he sounds like a very normal puppy... you will have calmer days and rowdier days. You will take two steps forward with training and then two steps back. You might have two weeks of excellent calm behavior followed by three days of puppy crazies.
He is a baby. I think people expect too much of young puppies and then think something is wrong when it's just normal puppy behavior. We see that they are capable of "getting it" (i.e., sit, walk on a leash, etc.) but we forget that they are too little for it to be 100%. Like my 18 month niece who sometimes uses the right word for the color of a certain toy (blue) and the next day calls it yellow. She is still learning.
