Bully Sticks and Beef Tendons Combo Pack Is a great treat for you dog. My dog is a border collie, jack russell, mountain dog mix named Eclipse and loved these treats. The first treat I had given Eclipse to try was the Bully Sticks. She was so excited and had taken it into her own spot to enjoy it. She liked the sticks so much that she finished her stick in one night. When we had given her the Beef Tendons they had lasted longer because they was thicker. I had given her this as a treat before bed and she had taken it to her crate and finished the rest the next day. She had enjoyed it so much she kept trying to get her own. The treats helped with her teeth and had let her have fun without tearing up her toys. I would highly recommend this product pack to anyone who has a dog of any size. I would say the stuff lasts depending on your dog in size and how much the chew.
