Input: Consider Input: I have this on auto ship because I use it so much. I have gone to every grocery in AZ and the cheapest place is Amazon! This is a great product and whatever you make using this flour will taste great. My son has Celiac and is allergic to gluten. I have tried every pancake mix and this one is the one I settled for!

Output: 5


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: Let's face facts, dogs will pretty much eat anything that you put in front of them - they really are not that choosy.  They drink dirty garden water, smell each other privates, and occasionally snack on cat turds, so trying to determine if a treat tastes good really is not that easy.  Having said that, my two medium size dogs (roughly 30 pounds each) absolutely love these treats. I like the fact that they don't have that smelly dog treat scent that most have (they smell more like people food - kind of like a ginger snap), and because they are harder and larger than my normal treats, the dogs must crunch them, promoting tooth cleanliness. But if you have a smaller dog (I also have a Yorkie), these treats are just way too large.  They are about two inches long and one inch wide (with a perforation in the middle). They contain organic ingrediants including carrots, apples and molasses, rather than fillers like corn meal.  They are relatively easy to break at the perforation - but really hard to break down further (though a hammer works well).  My Yorkie looked down at the treat then looked up at me with an expression of "you gotta be kidding me" and stared at me until I gave him one of his regular treats.  The only drawback is that unless they are purchased in bulk, they are a bit expensive, so I would not use them as a training treat. But for the occasional atta boy treat - my older boys love them.
