Red Handed.

I caught Abby feeding Riley her dinner tonight.  I was stunned.  She obviously did not like what I had made.  I am not sure where she learned this little trick, but thought maybe we'd have a few more years before one of the kids tried it out. 

I sat her down and without getting authoritative and just preaching to her about not feeding your supper to the dog, I explained the consequences.  We talked about how some foods are not safe for dogs and she doesn't know which foods those are so its best not to feed him anything to be careful.  Hopefully she got the idea.
