Anyone bought a buster cube? I am wondering if the size of the food hole is bigger, or it is just the cube that is bigger with the different sizes? I'd like to buy one for our 3 month old lab puppy, stuff it with dry food. I am not sure what size to take, 3.5 mini, 4.5 original or 5 inches large size?

One of the big advantages of the larger sizes....they don't get stuck under furniture so much! My kids don't bat them around like they used to. They roll them quite slowly and deliberately now.

If you get one too big, you run the risk of the puppy being afraid of it. If you get a smaller one, you run the risk of it being too small too soon for the puppy.

The size of the holes is adjustable at least in the larger ones.. don't know about the smaller sizes.

I agree with TooneyDogs. Not having to retrieve it from under the furniture every 5 minutes is a huge plus.

Personally, I'd go with the larger one, but that's just me.
