I just got the great maze dog game yesterday and I am already impressed! We recently rescued a 2 year old Labrador/Newfoundland from the shelter and he LOVES to chew on everything - especially when we are at work and he is home alone. From the time I unpacked this toy from the shipping box he has been focused on this toy and getting his treats out of it. It keeps his attention while we are gone as well because I am not coming home to find our valuables chewed to pieces anymore. Thank you, this is going to save several of my pairs of shoes!
