Boomer has heaps of nicknames: Boomey, Bubba, Poo-Bum when he's cranky (Poo for short), Bubby, Boofhead, Boofa (my husband calls him this), Mr Magoo (or Magoo for short), or sometimes a combo like Poo Magoo..he responds to most of them too!
Abbey my rotti has nicknames like: Ab, Abba, or Miss Abbey..she also responds to most of them.
Thank goodness I'm not the only one who comes up with a whole heap of weird nicknames for my dogs..especially ones that don't sound anything like their names... like Magoo my nickname of the moment for Boomer!
