I can completely understand what you're going through right now! My Tobi behaves the same way sometimes, so I asked our trainer what we should do to "fix" the situation. Our trainer told us that we have to "change" his behaviour by re-directing him to some more productive behaviour like training tools. If your pup is acting up, start practicing the "sit", "come", "stay" kind of stuff and reward them with tons of affection and a few treats. We tried this today when Tobi was turning into a terror, and it worked REALLY well! Good luck to you and your fur baby!!!
