The rubber toy stuffed with treats, popularized by the Kong brand, has become a classic of canine enrichment. A Dutch study measured precisely what it changes in a dog's behavior. All our comparisons are gathered in the dog toys and enrichment section.

What does research show about this type of toy?

A study by Schipper and colleagues, published in 2008 in Applied Animal Behaviour Science, observed eight dogs in a kennel-type environment before, during and after the introduction of a Kong stuffed with treats (study on Google Scholar). The toy stimulated food-seeking behaviors, increased overall activity level and lowered barking frequency, a set of signs associated with better welfare in a confined environment.

In which situations does this toy really help?

Does this toy replace real quality time?

No: the study concerns a reduction in stress signs in a confined environment, not a substitute for interaction with the owner. A dog left with dispensing toys all day alone is still missing out on socialization, a need these toys do not fill.

How to use it well day to day?

Varying the filling (kibble, food paste, soft treats) and the difficulty prevents habituation; a toy always filled the same way quickly loses its stimulating effect. Some models can be frozen, extending occupation time during longer absences.

What budget should you expect?

A sturdy rubber dispensing toy costs between 10 and 25 € depending on size, a durable investment for a dog that doesn't destroy it within minutes.

Frequently asked questions

Which model should you choose for a heavy chewer?

An extra-durable rubber range is preferable, in the same spirit as our toys for heavy-chewer dogs.

Should the toy be removed once empty?

Not necessarily, but a toy left permanently available loses its novelty effect and therefore some of its stimulating value.

Is this toy suitable for a puppy?

Yes, by choosing a size and hardness suited to their age, with supervision during the first uses. Find all our guides on the dog hub.
