I have an ongoing interest in activities that require Penny to think and, to judge by the wagging of her tail when she's solving problems, she loves to do so. On February 2nd this year I wrote about a toy I'd found that has her thinking. I'm pleased to say she still gets lots of entertainment out of it when we give it to her - not too often, because we like to vary her toys. On 14 December previous to that I had visited a German site and found lots of ideas for home-made intelligent toys.
Today I received a newsletter from the German site, called in English 'fun-for-dogs'. They've had a competition for people to invent more such toys. The results are fascinating. If you don't read German you could still browse the page, because many of the photos are self-explanatory. Just be aware that these games are for playing WITH your dog. Many of them would be very dangerous if you weren't involved in making sure your dog solves the puzzles gently.
The one I love is simply the use of a furry puppet to open its mouth and reward your dog when she does a good trick or anything you'd like to reinforce. It looks like fun! The photos are at the last ones on the competition page.
