I got suckered with a "100% guaranteed authentic" FAKE Juicy bag and mine does have the hearts on the feet. The fake ones do usually have shiny charms and this one looks authentic to me. Sugar is 3 lbs and fits nicely in mine. Spike is 4 lbs and fits but it's a little tight. I wouldn't think it would work for a dog much larger than 4 lbs.
Good luck selling it. It's a cute bag and a great deal!
