Example Input: 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.
Example Output: 5

Example Input: When I read the ingredients of these treats I thought for sure that my dogs would like these. I have 3 large breed dogs which usually love to eat just about anything. I have Rocky, a black and tan coonhound, Buddy, a blue heeler and a very large pit bull named Hutch. Rocky and Buddy have turned up their noses in disdain to these treats everytime I have offered them. The pit bull Hutch will eat them very grudgingly and even then he'll leave half of the treat on the ground, this is odd because, he'll eat just about anything including tree branches. So, I wouldn't pay the higher price for these treats, my dogs just don't like them.
