When visitng my grandchildren or when they come to our home ; I'm worried about a problem escalating. The last three times we have been all been together--when "REO" (3 yrs. old and a whole 6 lbs.) finally gets to relax and one of the kids gets close --he proceeds to give a short little bark ( like an alpha acknowledgement) in their face.

My fear is that since my grandchildren are 5 and 3 years old; they don't really understand when I tell them he needs to have some quiet time and space; don't put your face in his-- the result might eventually be a BITE!!!!!!!

Do I try teaching my grandchildren correct ways to approach and to reteach " REO" that his action is not acceptable.

Anyone have some suggestions.

I would be inclined, just for safeteys sake, to act on both your suggestions.
Its a great idea to teach the grand kiddies, ragardless of your dogs behaviour, the right ways to approach any animals, particuarly dogs, it is a very valuable lesson for them to learn.

I would also teach your dog that it is not acceptable behaviour, whilst from the dogs perspective you can understand the reaction,(well i can anway) for the safety of humans (particuarly the little ones) your pup should be desensitized, and taught to cop it on the chin (for lack of better words)and deal with it with some manners.
