Carst and a bone

Last weekend Carst got a present from our neighbours: a bone made of buffaloskin.
He chewed for three days and it was gone. Good for his teeth, as they say.
His former ownner was a bit afraid to give him such a thing because his stomach sometimes troubles him.
But: this went well!

So we bought him another one, according to the pet-shop owner the quality of this one is better. But: Carst just looks at it, sniffs at it, walks around with it, but: does not chew on it!

We wait and see what will happen....
