This oil is wonderful. I've had almond oil that was so strong it overwhelmed what I was using it for (salad, cooking). I loved the flavor of this oil and will be buying more.

Ex Output:
Positive

My dog loves this food, and she has maintained her healthy weight for many years. The vet is very happy with her general health, coat, and teeth. Having the 16lb bag sent directly to my home without any shipping charges is terrific! The 16 lb. size is not available in my area.

Ex Output:
Positive

Ex Input:
I used to buy this at a local health food store and then they stopped carrying it. Then I was thrilled when I found it Wal-Mart, but then they stopped stocking the dry kibble and now only carry the Newman's doggie mush in cans. So, I couldn't believe it when I found it here - Amazon really does sell just about everything! My Shih Tzus like it and they do not get sick at all like they did periodically on the non-organic but still expensive, "vet-recommended", brands.

Ex Output:
Positive
