A hollow rubber ball treats can go inside — chewing works the gums along a toothed groove.
Highlights
Treats go inside – It's hollow, with an opening at each end, so a filled ball keeps a dog busy long after a plain one has been abandoned.
Toothed groove round the middle – The ridges work along the gum line while your dog chews.
5 cm across – That's a small ball. If your dog is big enough to get it behind their back teeth, size up to something else — this one suits small and medium dogs.
Solid rubber, and it bounces – Unpredictably, which keeps a solo game going.
Six colors – Green, orange, yellow, red, light blue and dark blue.
