Two things that I have noticed negative:
- He is a little harder than the Kong Extreme toys, thereby he does not jump so well.
- The continuous opening for feed is too long and the rear too narrow for the dogs tongue. You have to stick cleaned regularly otherwise it gets disgusting (so for me, because dogs love so rotten stuff especially, perhaps, therefore the long opening is indeed intent ;-)
- It exists so far with us in only one color. If there are several dogs it is therefore difficult or impossible to assign any color.
Positives:
- So far more durable than the Kong.
- You find it just fine again. The black color of Kong Extreme was chosen simply not sent.
