My dog is obsessed with tackling and biting the punching bag and speed bag in my grandmas basement. She chooses that over treats. How can I break the habit? She's an 11 month old AStaff. Good girl overall. Her main issue is jumping on people and her urge to play with other dogs on walks. That is normal puppy behavior but I'm working on it. 

There's a punching bag in my gmas basement that drives her nuts. She jumps on it to move it and it pushes her back. She's been getting a bit excessive with it so I thought I could take the opportunity to practice 'drop it' and 'focus'. Frankly treat or not its as if she doesn't hear me at all. I figure if I can solve this problem other 'distraction issues' would be cake. 


What should I do? Strengthen the drop it command with better treats and try again?
