Years ago I had an Old English Sheepdog who loved people food. It wasn't particularly good for her sensitive tummy however, how could I possibly deny her a morsel every now and then
I got into the habit of saving my 'last bite' for her - always. The habit stuck, even after she had passed. For a very long time, I could not eat my last bite (of anything) because it was being saved for my baby dog
How well do your kids have you trained?
