The little rescue cocker had obviously never encountered this before because when we took his bed out of the kennel for an airing, we discovered, buried under his blanket, a collection of dog biscuits that had accumulated over several days. This went on for a while but needless to say he has cottoned on and we only find crumbs now....
I think I posted this before but our recently departed JRT would collect eggs from the hen run and bury them in a throw on the sofa - she never broke one, bless her!
