"The Thinking Person's Pet Food"™ – Since 1979


My dog has many allergies and that is one of the reasons I buy this higher end food. I am disappointed that you are not specific and transparent about your ingredients. If you are easily able to justify the use of porcine plasma, why not just put it out there on the label?

Because of your incomplete labeling policy, my dog experienced an exacerbation of her symptoms and I am not happy about this at all.

Labeling regulations by the government are strict and do not allow such distinction on a label. Specifics on ingredients, such as animal plasma, is located on our website in the Learn section. It is also available free to customers by mail if requested.

You also didn't mention how long you have been feeding the Duck Au Jus™, but it has contained the porcine plasma for at least 5 years. The formula has not recently changed. If you are feeding this food exclusively, it is possible she now has an intolerance to it. Feeding any single diet exclusively long term may actually create food intolerances and allergy problems. We recommend a rotation of the dry and canned Wysong diets as part of an IV (intermittent and varied) diet with a variety of fresh, whole foods and raw meats.
