Lesson: Mathematical Manifolds
Smart dogs tend to be the most interested in things you do not want them to touch. Lots of exercise every day can wear them down, but they bore easily and may try to learn, for example, what exists inside your couch cushions or underneath your carpet.
No one needs these investigations, so occupy their minds with Kong Genius and other tough-to-solve puzzle toys. Pop a treat in either the Mike or Leo models to help your dog appreciate the nuances of mathematically beautiful shapes -- and the frustratingly complex openings the treats must pop out of. If your dog is on tenure track in solving puzzle toys, grab both the Mike and the Leo, then connect them together. Another good puzzle option, with three different shapes that fit together, is the Busy Buddy Linkables set.
