Abby my Jack Russell took to them right away. As I am typing this she runs up the steps and sits at the corner of my bed next to the chair near my computer. I also ordered one for my daughters little one who now has to wear a brace from jumping on and off furniture that damaged her spine. Little dogs should come with a warning (please get me steps.)We don't want the same thing to happen to her little brother. Great price as we have been looking around.
