“No” is a word that even well-behaved dogs hear often. My two dogs, who are somewhere in the middle, hear it all day long. “Lucy, no biting your brother’s tail!” or “JJ, stop eating your sister’s food!” are said over and over again. What if I could teach them the word by sight? It would save me a lot of energy just to pick up a flash card and shove it in their adorably naughty faces. That is sort of what this Dog Gate aims to do. Stop them in their tracks with a barricade and a giant red, lacquered NO!, and maybe, just maybe, they’ll get the hint.
