Ex Input:
The last bag of these I got from Amazon had a lot of hollow bisquits.  It was weird ......  they just weren't solid like they should be.  I'm going to switch to another brand of grain-free dog bisquits now as there's no sense in paying for something I'm not getting (and these are expensive!)  And if it wasn't for the good packaging I'd wonder if bugs had gotten to them..... but I don't think that's possible.

Ex Output:

Ex Input:
It may be all natural but it didn't have a natural taste to me.  The can size is small and the calories were more than I thought there should be.  I like the mild carbonation ok but I wouldn't switch from orange juice.

Ex Input:
My sister is alergic to wheat so I make her a lot of Gluten Free foods.  I searched local stores and could not find Sorghum Flour.  So I looked on Amazon and finally found it.  It was all packed wonderfully and arrived perfectly fine and I'm already using it.
