    So adorable

    By on

    This is the most adorable costume ever! I’m gonna be sully and my dog is gonna be in this Mike costume. I ordered a large but it was too big. I contacted customer service to make a return for a smaller size. This amazing company sent me the sweetest message and told me to just donate it and gave me the refund so I ordered a Medium and it’s perfect.

    this was a great size for my dog .. but what I didn't know is the front of the costume is like a pillow so it made it impossible for Our 9 lb dog to walk.. its super cute I think she's to small for a costume like this but it is made well
