training my great dane??

I have a 1 1/2 yo great dane. He is the GREATEST dog I have ever had. He sits, stays, speaks, shakes, comes, stays etc... I don't even have to have him on a leash in my unfenced back yard or the park or where ever(i do for legal reasons when required).

OK so the only thing I cant get this great dog to too is STOP EATING OFF THE TABLE,TRASH and anything with people food on it.

I have had the dog for a week. I do not give him people food, but the previous owner more then likely did.
Yes this dog is very smart. NO does it and he backs away, but he will come back and do it right in front of me like its nothing
"donna and jesse" great site and you know your stuff.

the answer is not to simply make it so the dog cant get it. I should be able to leave a t-bone steak right in front of my dog and say one command and he will NEVER even look at it unless I say its ok. any dog can be trianed like that and I have trianed this dog a lot in a week, but I was stuck on one problem. sorry, but if you just make it so the dog cant get it then you are not trianing your dog.
