After being without a dog for a year and a half, I feel it's time for me to have another in my life. And, coincidentally, there's an Irish wolfhound mix at a local shelter that I like the look of.

Being the contrary (controlling?) person that I am, I don't want a dog that will respond to everybody. So I'm considering teaching him to respond to commands in ... Gaelic.
Would the Gaelic speaking members of the Rabble be able to help me out here with some basic phrases? "Sit", "Stay", "Down", "Come (here)", "Get _", "No!" are the sort of things I have in mind. Irish or Scots Gaelic doesn't matter, though I suppose with a Wolfhound mix Irish would be slightly more appropriate.

One last thing - since he'll be beginning a new life, a new name may be appropriate. Are there any Gaelic homophones for "Rudy" (I thought I would start with names that sound similar to the one he already has)?

Thanks
