Not sure if Smokey's bad habits should be considered a ringing endorsement of the practice...

But when SmokeMutt arrived at our Ranch as a half-starved 1 year old - the Boy could polish off an almost 2 cup serving of Krunchies in about 6 Bites!
(And he didn't waste much time breathing during a meal!)

He'd mouth up a mouthFULL and SORT OF take a giant KRUNCH - ONE Time; then just *GULP* it all down. Not till he was in bowl clean-up mode (when there were only a few scattered pieces left) did he actually "chew" more than twice on a mouthfull.

I swear he spent more time licking his chops AFTER the meal than he spent eating!
And there was often a lovely BurRRRRRP! to signal "I'z dun, Dad! Mmmmm, GUD!"

Took almost a year for him to realize...
A) He WOULD get two meals, every day;
B) Nobody was going to "steal" his meal, and
C) He could slown down an chew the stuff!
