Durability: *Tough Toy*
 
These are really tough and durable - we have had ours for years and it has survived countless foster dogs and puppies!
 
For dry food only, it has a removable core for easy filling and a maze structure inside for slow release of the food, encouraging your dog to work that bit harder. The cube shape is a little more difficult to manipulate than a ball too.
 
We think this is an essential for every activity toy collection!
