Input: Consider Input: I have three Newfoundlands so we go through a lot of food!  One of the dogs has had severe health issues and since we've switched from commercial kibble to home made food, he's thrived!  He gets regular blood tests to monitor the drugs he's on and they have been perfect since we started on Sojos!  It will not cure his issues, but he has more energy and he can't wait for meal time!  The other two are glowing with health as well!  All three dogs coats are shiny and they have tons of energy (for a Newf!)

Output: 5


Input: Consider Input: We are Chocolate Moose & Mickey Moose,  Our nice owner bought this great food for us.  We love it very much, I have gained 5 lbs. because I eat all of Mickey's food when he isn't looking!  Our skin and fur is much better now too.  :)

Input: Consider Input: I have had to cut back on caffeine recently because of heart palpitations that seemed to be made worse by all the coffee I drink (5 cups a day, maybe.) So I am mixing 1/3 Melitta Colombian and 2/3 decaf. I substituted this for the other decaf I have been drinking and found that it has a rich smooth taste. Very little to none of the burnt taste that decaf often has. The price on amazon makes it a pretty good buy as well. I don't care for the packaging, however. I couldn't get it open without cutting the top, and then I had to transfer it to an old coffee can to store it, with all the mess that that entails. If it were in a can, I would be more inclined to buy it. But the taste for a decaf is quite good.
