To keep up with our Free Dog Food Samples and Coupons area, I continously scour the net for dog freebies. I think I’ve found another good one. You can get a free sample of Natural Nibbles upon request. I hadn’t even heard of this particular treat, but the ingredients look really good. After searching, the only place I’ve found these for sell is on Amazon. Anyway, it looks like they offer four varieties – beef liver (with Glucosamine and Chondroitin), chicken liver, salmon treats, and 100% beef liver.
