Tasting the air
When I use my excitement-voice with Connor, he reacts by licking the air. He can't help it - Dachshunds are famous for being a "licky" breed and his sense of taste is crucial. As he encounters the world around him, his tongue leads the way, slightly ahead of his more prudent nose.
This means that his tongue goes places where angels fear to tread; of this we need say no more.
Let's simply pay tribute to the pink miracle that is a pet's tongue - and to the fact that pets are a lot less shy about showing them off than humans are.

Here's a cat's tongue doing its job, as Nitro grooms Cullen. The natural velcro of a cat's tongue allows the cat to groom itself to a state of perfect scent-free cleanliness - just what a predator needs in the wild, and one of the things that make cats such things of beauty.
