Not one member of my family, including me, like these extremely salty, much too strong a BQ taste to order more.  I purchased them on a recuring basis and i wish to cancel now.  I have received only one shipment. Cancel further shipments.  Not to our taste at all. These are Lowery pork rinds.

THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?

We fed this to our bulldog when she was a puppy, and at first she did wonderful. Then the corn and preservatives took their toll.... She was itching and had a chronic ear infection and her face had a terrible yeasty smell ALL the time. She licked her paws constantly and scratched her face raw on any surface she could find. Then she started vomiting. We HAD to change her food. Now she eats a fully carnivorous raw diet and is thriving! No more itching, no more ear infections, no more yeast, no more paw licking.
