quick update, since this has been quite an ordeal for us…went back to PetSmart to return/exchange the EasyRider harness on our way to Kansas City. The employee involved her mgr in our conversation, since she had no idea what to suggest. We walked out with an American Tourister seat belt harness, and so far, so good. Pippi remained strapped in during our short jaunts around the city, and also during the 500 mile trip back home, whether from travel fatigue, disinterest, or inability to escape -- who knows! In the meantime, we'll continue to set her up in the harness and hope for the best!
