We have been giving our 100 pound shepherd/lab/collie/husky mix Hip Action since he was a pup. Our vet believes this is realy going to help him prevent all the hip problems that shepherd's usually have. Eventhough I cannot buy it locally, I make sure to buy it on line so my boy will remain healthy and happy!

Ex Output:
Negative

Because they brought bagels to America without which we never could get maximum level of enjoyment out of this delightful low cost caviar.  Caviar for breakfast!  We use the small soft plain bagels cut in two upon which we smooth a bit of cream cheese then a nice ring of caviar in the center of which is colorful and delicious cut up hard cooked egg then add a perfect cup of coffee.  This is is best done on a week end so it can be savored ever so slowly--no stress involved--pure luxury.  Yes, Yes, Yes, yes, yes.

Ex Output:
Positive

Our family loves SPAM and Amazon makes it so easy and such a great deal to buy in bulk.  The 7-ounce size is perfect for our use.  Amazing what you can use SPAM for.  Add it to all your favorite recipes in place of other meats!  Super convenient to have it come in automatic shipments without having to give it a second thought!
