Good product overall but the last order I received in mid January the expiration date is April 2012! We will have this product for the next 6 months which means for the month of May and June will be giving our dog an "expired" product. We are located outside the US which means we have to pay close to 40$ in shipping fees. When we called Entirelypets.com we were told we could return a few boxes but that's all they had in stock which means we would have to pay double the shipping fees again when the new stock arrive..... so we opted to keep this batch.
