Has a backpack limited your GSD's lunging?
I've posted in several threads recently about my newly adopted four-year old's friendly lunging and barking when he's on a leash. The last few days, I've been experimenting with walking him with a backpack on him, carrying half a gallon (c. 4 pounds) of water in each side pocket. He weighs 80 pounds.
First results have been very encouraging. He notices people, but doesn't bounce toward or bark at them. He's still barking at dogs, but starts later (and ends sooner), and seems much easier to control. Anyone else have similar or contrasting experience? Will he revert to form as the pack becomes second nature?
