Warm And Fluffy
The animals have hairy fur.
The birds have got their feathers.
These keep their bodies warm enough
throughout the chilly weather.
The fibres in those fluffy coats
criss-cross to form some air-holes
that can’t escape or waft away
because of all the hair-folds.
Their skin gives off some body-warmth.
Just like a radiator.
Their fluffy coats help keep that heat
as thermal insulators.
The warm air’s trapped inside the fur
to shield them from the outside.
The way that blankets on a bed
are cosy on the inside.
But if that fluffy coat gets wet
those air-holes fill with water.
Their body’s warmth escapes as that
wet coat’s a heat conductor.
The soggy fur clings to their skin.
No longer insulated.
And water makes their body cold
as it’s evaporated.
Any fluffy animal will
shake that water well away.
So if your puppy’s had a swim …
Watch-out for all that water spray!
When it comes to having a fluffy coat, it’s a good idea to shaking off any water, so as not to get cold. Dogs are the best shakers! I love the sound of their lips and soggy ears slapping their head as they do it.
