6 omdömen förKONG Extreme Goodie Bone

I have 6 kong things now for my 4 dogs and there is only 1 that interests them: a cube with holes in different sizes and different sections to put treats in. I expected this 'goodie bone' to be hollow so I could put in treats. However, it has 2 holes in which I do not manage to 'stuff' anything other than perhaps with something spreadable or expensive Kong treats. Dogs are not interested in it at all. Postage in Sweden costs too much , so sending back is no option.Total waste of money.
