Glug
* "Me-at!" Translation - where did you go without me?
* gurgle, gurgle (his tummy 24/7)
* "Hmmph... hmmmph!!!... Hmm-ack! Ackk! Akkkkk!!!" (3 times in a row) - hairball
* "MEAHHH!! MEAHHH" (at 90 decibels) - it's 5 am why aren't you up yet
* "Now" - now!!!
* "enh.. enh... enh" - snoring
* Mrrrow - get me my fish
* (Mrrrow now - get me my fish NOW!)
* "mh?" - what or who me (depending on context)?
* The sound of a rotary engine - how he "sings" himself to sleep
* "Rahh hemm armahh!" - how dare you leave and not tell me first!
* "Meow" - the dog showing he can speak cat (only the dog says meow)
You say, "used," which leads me to believe deceased.
I would like to add, any dog that lives that long shows he/she lived and wanted to live a long and happy life.
Even though you don't get that "Chomping, snorting, and sluping," sound to be irritated or concerned about, you raised a good pooch who lived a happy life. :) :)
