I think this is a great idea... for dogs that don't chew things I know many dogs that would rip this thing apart in minutes. I think it would work quite well for both of my dogs, my two are very practical with their paws so would quite enjoy pushing it around like that. Koda throws his Kong at the ground to get the stuff out rather than licking it
Not to mention the STUNNING Belgian Malinois, love those dogs, they're so gorgeous!
ETA: I think i'm going to make this my new project, the dogs would love it.
