A dog that is fluffy, looks like a puppy but isn't and is so cute you can't help but mix in a little baby talk when referring to it; hence the double "o" at the end of the word.
You're dog is soo cute it must be a Fuppernoo!

Some day when you're no longer a cute little puppy I bet you will be one of the cutest Fuppernoos in the whole wide world!
