We'd all love to know what goes on inside our dogs' minds - and it seems scientists have got one step closer to finding out.
A new study has revealed how dogs think about their toys, including how they identify their favourites and imagine familiar objects.
The study was published in the Journal of Animal Cognition by researchers at Eötvös Loránd University in Budapest, and examined how "typical family dogs" use smell, vision and texture to identify teddies, balls and games.
