In humans, aging hastens declines in short-term memory and logical reasoning skills, making it more difficult to learn new tasks. Previous research has found similar declines in dogs, but long-term memory is a little-known aspect of dog biology. (See "Many Animals—Including Your Dog—May Have Horrible Short-Term Memories.")

That's why Wallis and colleagues are studying how dogs both young and old memorize tasks, and whether the animals can remember them months later.

The results are still in the works, but Wallis expects to discover that it's tough—but not impossible—to teach old dogs new tricks.
