I have a 110lb 2yr old long haired black, GSD. He goes CRAZY over these treats. The variety is perfect for him. Some are chewy, some are crunchy. The trachea tubes are a huge hit!! He sees me getting one out of the bag and he runs to his cozy "place" or outside in the yard to gnaw and chew. Since he is so big and his mouth is enormous and strong, he finishes the tubes within 20min. However, he is a very happy boy and I am a very happy mom. These products are completely worth the money.
