My German Shepherd puppy is now 11 weeks, and uses the Kong really like. We lubricate liverwurst at the opening, but I make sure that it is not too far inside. The clean is one thing and the small no longer gets the then beyond. Furthermore, I ask him not continuously available for the puppy using it else to chew on it.
The pity is that unfortunately does not match the color of the product image. He is in a complete Baby Blue kept like this one
From the functionality 5 *****, but it should then have the figure correspond.
I hope I could help you, and otherwise questions via Kommi !!! ;)
