do these have preservatives in them?

Ingredients list: Omega3 fish oil; Omega 6 (Borage oil); Omega 9 (flaxseed oil); Vitamin E; Dicalcium Phospate; Desiccated Liver; Microcrystaline; Microcrystaline Cellulose; Natural/Artifical Bacon flavor; Magnesium Stearate; Stearic Acid; Silicon Dixoide; Calcium silicate. I can tell you that this has really helped my dogs. Keeps them from scratching so much & chewing the heck out of their paws. I hope this helps.

Are your products made in the usa ? thank you

Dear Darla, Thank you for your question! Yes, all of our products are made in the USA in FDA certified laboratories! Have a great day.

What if my did doesn't like the flavor? Can I return them?

My dog never takes any pills I always put the pill in peanut butter on a spoon Teddys peanut butter no salt no sugar

I have a Rotty, will this help with his dry white flakes and licking his paws and itching?

I believe that it will help. I have a black German Shepherd that I rescued a year and a half ago. His skin was flaky and very dry. The itching was terrible. I have used this product daily with him and now his coat is shiny and the dry skin is gone. Hope this helps.
