Good Sized Treat for a 35 llbs dog, smaller it will interfere with daily meals.
Flavor Name: Chicken Chips, Size: 1 Pound (Pack of 1)
The texture is hard as a chew treat, my two small dogs can smell the container being opened and tapping my leg to give it all to only one. Size is one chicken piece rolled tightly, so i have to cut it up completely and share it between my 15 yr old MinPin and my 2 yr old miniature shepherd mix. This will be used only every other day so it will take about a month or more to us first of two bags. The cost also drew my eye and the fact that just two ingredients which should not affect the health of my MinPin.
