Krumm is going on 8 months, and he appears to be somewhat nervous especially on walks. I use a pinch collar to help control him and that is working. I want him to be more confident and enjoy walking. I know he likes to go as he is always ready for me to put on his collar, but he gets spooked easily. Is there anything else I should be doing besides repetition? I understand that is key. Thanks!

Sounds good. If you don't already, you may also want to counter new experiences with treats, rewards, and praise, making them seem less scary to him.
