Hi everyone, I'm a new Doberman owner and I'm having some trouble controlling my 9-month-old puppy. He's extremely energetic and mischievous, constantly getting into things and disregarding commands. I've tried positive reinforcement and basic obedience training, but he seems to have a mind of his own. I'm worried that his behavior will become a problem as he grows older, so I was hoping to get some advice on how to better control him. Any tips or advice would be greatly appreciated. Thank you!
