"What's that smell?" is something we ask each other every so often.
If dogs could talk, it would be a constant discussion topic, because they smell so much more than humans can.
It's a subject Alexandra Horowitz gets deeply into, in her book Being A Dog.
And just so no one thinks we've gone completely to the dogs, we give equal time for cats in this hour.
Or would have, but our cat guest had to beg off late. We'll re-schedule with Sarah Ellis on cat training, if possible.
