Four geometric shapes in premium natural rubber, co-designed with an aerospace scientist — the point of the angled faces is that the toy never bounces or rolls the same way twice, so a dog that has lost interest in a plain ball has something to chase again.
These are the solid versions: grooves hold treats or peanut butter, but there is no hollow core. If you want to pack a full meal in, the Chewtastic GEO Fillables are the ones with a cavity. Rated for medium chewers — a dedicated destroyer will get through natural rubber, and puppies or older dogs are better on the softer Gentle edition.
Features
- Four shapes — Geo-AstroRolly, Geo-Duo, Geo-Gem and Geo-Hex.
- Unpredictable roll and bounce — the off-centre geometry does the work, no batteries or moving parts.
- Premium natural rubber — renewable material, tough enough for medium chewers.
- Takes treats — tuck treats into the grooves or smear with peanut butter for a longer session.
Care
Rinse in warm water and air dry.
Safety
Supervise play. Inspect before each use and retire the toy once the rubber starts to tear.
