Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.

I'd never heard of this brand but they were very cheap here on Amazon and I was extremely surprised at how good the Dark Chocolate Hot Cocoa is. Absolutely worth trying, it's really quite good.

It was bad before we open them. I saw them when we got. I did open. It had some spot green color. I did not know what it was. I was very upset. Do not buy this product.
