Another Clever Auto Tag

I was driving behind a minivan today that had an oval tag of some sort on its rear that was difficult to read. All I could make out was “wag more,” which didn’t seem to make much sense. I couldn’t read the smaller type below it. At a stoplight, I was able to get close enough to make out all the text, which I though was cute:

wag more
bark less.
