Input: Consider Input: This bone is nothing more than a big dog treat.  I have a 2 yr old Pit who ate through the souper in 5 minutes.  After reading other reviews I took it away from him and will save the rest for a later date.  I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat.  Will not be buying this again.

Output: 2


Input: Consider Input: This is the pancake mix we go to when we don't have buttermilk in the fridge (don't think the vinegar trick is worth it so we always do fresh) to make Alton Brown's buttermilk pancake recipe.  This Stonewall mix is a good option and the flavor is the best of any store bought mix by far! It might cost more, but it really is superior to the other prepared mixes.

Output: 4


Input: Consider Input: With any low fat or low calorie food, you're going to sacrifice taste of portion size.  With this product, you sacrifice both.  It's a good idea, which was done well with the Oreos and others in this series of "100 calorie" snacks, but I think you're better off with a single cookie from the regular Chips Ahoy box than a whole bag of these.
