Sounds like odie taught his mom a thing or two
. Maybe he is just letting his "guard" down more at home, kinda like we do. I think with a little patience he will not take food anymore. My little girl will not take food but she will sit next to you, my little boy (rather new to our home) is in the process of learning not to approach people with food. He sounds wonderful though, and do not feel bad. We all want the best for the yorkies we fall in love with and sometimes what we thought was going to be great for them turns out not to be needed after all.
