This food is great - all ages dogs.  I have a 3 year old and a puppy.  They are both so soft and hardly ever get sick.  The food is good especially when you have Amazon Prime shipping  :)

Ex Input:
I ordered these to make s'mores. I liked the ingredient list, no HFCS. However, they come more like a box of Wheat Thins. They are not large enough for s'mores, and many of them are broken upon arrival. They do taste good though, as a sweet snack.

Ex Input:
Ordered this plant to remedy a fruit fly invasion. The amazon shipping was acceptable, but the manufacturer does not create the packaging to facilitate any shipment, unless they were to put "This side up" on the box. The dirt was everywhere but where it was supposed to be and the plant (Audrey) was upside down, roots up in the box. If I had found one locally I would have bought it there. Hoping Audrey survives, but I don't have high hopes. EDIT: Audrey is now deceased. Do not recommend.
