Dont be sad..you're not alone. Pasquale responds to the word STOP ..so when he starts to bolt, i'll use that word. BUT i dont trust it..cause if theres another dog around or something he's really interested in...he gets "Yorkie A.D.D. " I know he will not listen to me.
SO in the interest of his safety..i ALWAYS keep a leash on him if he's not in a secured area. They sell really long leashes..just get one of those.
