As far as ingredients and flavors, Zuke's is a favorite in our house, But the shape of these bones proved to be very dangerous. The 'balls' at the end of the bone are the perfect size to get stuck in your dogs throat to choke on. This is exactly what happened in our case, but thankfully I was able to stick my finger in his mouth and dislodge the ball. I never bought them again and have since read other reviews where similar situations happened. Thank goodness I was there and watching him while he was eating!
