Dough is a common way to misspell the proper name Doug. There are
two very frequent occasions that you
will find this form of misspelling.
1. Hispanic population – especially when ordering late night fast food at Whataburger and they have to
ask you for your name to call your order when it is ready.
2. A typo on the keyboard because the letter h is right
next to
g so people type the word Doug, but accidentally add the h at the end. Spell check cannot pick this up because dough is still a word.
