Oh my .... in quest to learn more about harness sizing, I happened upon a PetSmart webpage referring to "Teacup Yorkshire Terrier."
Oh my, oh my.
Hope folks will contact PetSmart's customer service line. Ask them to use the term "small" instead of "teacup" in order to promote yorkie health and save the lives of countless little ones.
I called customer services (1-888-839-9638) and also used the "Leave Feedback" tab to send a written message.
