Thanks so much, everyone! Trisha, I'll be sure to check out those articles. G-Diddy, I'll be emailing Mrs. G-Diddy. I think we'll try hand-feeding him at times, too.

Last night we enjoyed a full night's peaceful sleep--no interruptions--a very good thing! However, we did have another growling incident. Murphy was standing by our bag of bottle recyclables, nosing around. I asked him if he wanted me to find a plastic bottle for a toy and put my hand in the bag. He growled at me and even lunged a bit! He was sort of "trapped" in a corner--the bag is behind our kitchen table--so he probably felt protective and/or threatened. Whatever we can do to stop this behavior, we'll sure try. I do NOT want to be afraid of my dog!
