It was quite fun at first, but then my dogs got bored of it. I have 2 German Shepherds around 1 year old. I think it is suitable for small dogs or puppies. To not throw it away, I attached it to a rope and tied it to a tree, and they enjoyed chasing it around. I also tried using it as a ball, but it would open up. It is quite durable and doesn't break easily.

Interesting for my dog. The medium food comes out a bit difficult, so it may be intended for smaller dogs.
