That leash looks nice and loose
Yup that's why I took the picture.
We use a gentle leader so her pulling wasn't terrible unless she was near her favourite place to play but she'd be super excited on her big evening walk (that one ^ ) and we'd constantly be trying to keep it loose.
The dog whisperer dude said although she wasn't dragging us down the street, she was being hyper vigilant and thought her "job" was to scan and make sure there was no danger to me or Mrs JBJ. Now she's learning her job is to walk nice next to us.
Same with barking at the window. She'll always be protective of the house but her job now is to gently alert us that something might be outside than to go nuts barking at the window and scare it off.
