Ex Input:
Short and sweet.....The product itself is top notch and my two GSD's love it. However, the last shipment looked like it was packaged by a three year old and thus it arrived via UPS with a can lid popped open spilling its contents over the other dented cans. Another case arrived seperately which was properly packaged using air pillows and was fine. Don't get sloppy Amazon. It will cost you customers.

Ex Input:
Yes, tasty -- but it takes a little getting used-to.  You have to like coconut to like this snack item.  That taste quite overwhelmed all else, for me.  I found few chocolate chips -- maybe they were all taking a rest when my snacks were baked.  Anyway, it's a chewy but tasty item worthy of your consideration.  Give it a try.
