Ex 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!)

Ex Input:
10 out of 12 cans are seriously dented , and, the dents did not occur during shipping. These were dented befor they were packed in the case of 12 at the factory. These will get trashed because it will be more of a pain to return them. I will never buy these again !!! Amazon did refund my money without having me return the cans. Cudos to Amazon. They are a class act!

It wasn't a bad purchase at just $9.99 through Warehouse Deals fulfilled by Amazon and shipped for free, but took 2 stars off because it wasn't a freshness issue but Cracker Jacks® just don't taste the same like when I was a kid back in the 1980's.
