if you cant prong,and training collars,then kodie was 3!!

Leather Collar-thats what he wears during the day when he's at home,or tied up in the front yard with us
Prong-he wears it when we take him for walks,we still have to worki on pulling a little bit with him.
Training collar-is for when i take him to Obediance class,or when im working with him outside.
