It seems to have become the norm in newpapers (and online news) to call dogs "pooches". Everywhere I look to read about a dog it's referred to as a "pooch".

Do you call dogs pooches? Do you know anyone that does?

A grown up dog is..... a dog. A young dog is a puppy (or pup for short).

Where has this word "pooch" come from? Anyone know?
