Example Input: I have been giving my dog this treat for a long time,I found it here on Amazon and it is much cheaper! Now I learned that ALL chicken treats for dogs (and also cats I believe) that are MADE IN CHINA are being investigated  by the FDA because some dogs have died after consuming them. These treats and all Dogswell treats are made in China,I researched all over the web about this matter and bottom line is: why take the risk? A few sites say it is OK, most say to be cautious and others say don't buy.I threw out all the ones I bought and got new ones made in USA.I wish Amazon gave us the choice of "made in USA", for now I recommend everyone that has a pet to read the labels of the treats and food. Sorry this product, I don't recommend.

Example Input: Go to Costco, and you can buy lower than this  price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz.  Besides, it is more convinient to return if you kid does not like this formula  Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

Example Input: After opening the box it looking like it fell down a set of stairs.  Most of the crackers in the packages were cracked and full of crumbs.  My husband is gluten intolerant and he likes these crackers.  I guess we won't be ordering them this way again.  We are both very disappointed.
