Oh yes, I see those same playful disobiedent behaviors in our Biscuit. He's 5 months old and I figured he's testing his boundaries. Running away, disobeying a down, jumping up on the counters, getting into the garbage, running out the garage door. These are all areas he was doing perfectly until we hit this point. He used to be able to be in the front yard without running away but now he just takes off and he won't come when he's called, even for a treat. It takes a lot more time help him learn to obey. We just keep being consistent. Enjoy, I do!
