8.5 month old GSD excitement - impossible to enjoy outside
my male GSD puppy Nyx is now 8.5 month old. We have been training and socializing from 2 month and to about 6 month.
He was the perfect and non excited dog up until 6 month. I had him everywhere, the bus, the park, busy city streets. He didnt care for anything. Confident pup.
At 6 month he started to have ears up in alert mode for the first time when he saw dogs. Now this has escalated to humans walking on the street. He's getting so excited/alert.
Before 6 month he never pulled on the leash. Now he can walk until he encounter any stimulus outside and its game over.
In my country prong/ecollar is prohibited so Im limited to lesser tools. I'm currently using a choker that is fit high behind the ears.
He's getting so pumped up that he ignores any correction I make now days. In the beginning I could suppress his reactivity. Maybe for the first month.
Now he's immune outside. I'm very frustrated. From nice walks and exploring everyday to being trapped on his potty street.
He is from working lines by the way.
I'm just hopeless what to do. We can train inside and be successful. But the moment we are exposed to stimuli outside my gate he's walking on his toes in excitement/focused and we take 1 step and he's ahead of me. If we try take 2 steps he's almost at the end of the lead.
What can we do? Are we doomed to training in my room and have reactivity excitement everytime we go for a potty break?
