Quoted from navajas:Regardless of whether or not you wish it to be so, "irregardless" is not a word.
Cute dog though!
actually, due to all of idiots out there, merriam-webster recognises "irregardless" as a word
http://www.merriam-webster.com/dictionary/irregardless
the sad part is that this word is a double-negative and serves no purpose since "regardless" means without regard, so "irregardless" means not without regard
