This is ridiculous.  The best gourmet ketchup I have ever tasted.  It is pricey, but wow..love this stuff.  It would make a great gift for someone who is hard to buy for but loves their ketchup.  Yummy!

My co-worker that does animal rescue brought in a 'Whole Dog Journal' recently and I was astounded at the feature article for that month which covered dog foods, I had been feeding my dog Beneful which is basically just junk food.  I switched her off immediately, hunted around on Amazon to find an all natural food and this fit the bill, shipping was free which was awesome and my dog LOVES the food, I worried about that b/c I've switched her before and she's been uninterested and I've had to top with gravy, etc.  Do your research, it will blow your mind what your pets are eating in regular grocery store dog food, it's typically a high ratio of corn which is a filler.  If you want your pet to live a long and healthy life what they're ingesting should be high up on your list.  I'm glad to have the knowledge now and I really wish I'd looked more into this with my two other dogs years and years ago.
