My dogs, two 50 plus pound Australian Shepherds go through treats generally in about 30 seconds. With the bully sticks they actually stop to chew. Some of these sticks are rather small, so I do not give the small ones to o my older dog, who will swallow it partially whole which is not good. However, to the nine month old puppy, it will keep him entertained for 15 to 30 minutes and has become a signal that it is time to settle down for the night. The smell is not great, but hey, it is a bull's penis. The value for the money is good, as bully sticks overall are incredibly expensive to buy anywhere. I like that they are in different sizes, and smaller. I use them when we take the dogs out and want to stop for lunch. Just pull out a bully stick and you can enjoy an uninterrupted lunch while you dog has its treat. For my dogs, these have been the best product for the money.I buy them regularly.
