Wow, what a brilliant product. These buffalo horns are the best thing I've found for my obsessive chewers. They are huge and very long-lasting, I estimate about three months of chewing for 2 x 20-minute sessions each day. Being 100% natural with no chemicals at all, I'm happy for my dogs to enjoy them without concern like other products. Customer care was second to none. Khalid was extremely helpful answering my query within a couple of hours, then hand-picking my order himself, plus adding a bonus gift for the dogs. Am I please with the product, service and cost ? 100% yes
