Please Note: Our bully sticks are very popular! And we loving sending out free samples to dogs who will love them. We are a small company, however and limited in how many we can send out each month. Each month we send out free samples to the first 150 people to sign up. If you do not receive your sample in the next week, please consider trying again at the beginning of next month! Thanks and happy chomping!
