My 180# English Mastiff, Lily, just LOVES the 12" braided Bully Sticks. It is difficult to find this big girl something to keep her busy for long periods of time, and happy. Well, your wonderful products are perfect for her. We are trying the large antlerz also this time. Lily thanks you for the speedy delivery and the informative videos describing the products. As shewatches the videos with me, she can then decide which products she wants to try next. Thanks for your great products..Lady Lily
