I have a GSD pup and a 2 yr old shelter dog (about 70 lbs) and they do the same thing. I think it's just the pup in them as to why their short attn...
The big one plays sometimes and gets too rough and I have to slow them down but the pup bo, just wants to keep rolling with the punches. Lol.
I'm not sure if its a bad thing I just wanted to let you know I'm in the same situation. About the training and all... Bo does what I ask but he's constantly looking for a treat in return
Lemme know if you find out anything
