Cookie taught herself a trick that she found very helpful: emptying the cat food bowls in no time! We're still working on that because we (the cats and me) aren't very happy about it.

Other than that? As long as it's about food, than Cookie likes to help emptying/eating it.

There's one trick that she taught herself which is quite practical: she goes into the lake and removes all cans by bringing them to me. I never told her to do it, but she's simply a Retriever and thinks it's great fun. I'm always a bit afraid that she might hurt herself. I put the cans in a garbagebag when she brings them and than we bring them to the recycling area. Cookie is usually very proud and waggles with her tail as if to say: I did it, I did it!
