Most treat toys stop being interesting the moment the food runs out, and most balls lose a dog's attention somewhere around the third throw. Putting the two jobs into one object is the sensible answer: something that bounces and rolls like a proper ball, with a hollow middle you can pack with a reason to keep chasing it. The chase and the reward end up in the same place.

It is moulded from natural rubber, which gives the irregular bounce a hard plastic ball never manages and enough give to be kind on teeth. The hollow cavity takes soft treats, wet food or a paste, and the rubber flexes as your dog works at it so the reward comes out gradually instead of all at once. It rinses out under the tap and holds its shape through repeated filling and emptying.

On chew strength: this is made for medium chewers, and a determined power chewer will get through it. No rubber toy is indestructible, whatever the packaging suggests. Check it over now and again, retire it once pieces start coming away, and supervise the first few sessions so you learn which category your own dog falls into.

Who it's for: Dogs who love a ball but lose interest quickly, fast eaters who need slowing at snack time, and households wanting one toy that covers fetch and enrichment.
